## Revenue Scale & Growth Durability

What the numbers say: Kirloskar Brothers Ltd is the scale leader at ₹4,664 crore, 72.6% ahead of KSB Ltd. WPIL Ltd's growth is 8.4% from a ₹1,977 crore base, with 15 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

Investor read: Kirloskar Brothers Ltd is the scale benchmark; WPIL Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Kirloskar Brothers Ltd's growth falls below WPIL Ltd's for two consecutive comparable reports while operating margin also compresses.

Evidence: Kirloskar Brothers Ltd · ₹4,664 crore | 72.6% versus #2 · KSB Ltd | 5/8 recent comparable periods | 4/4 companies · 69 observations

Definition: Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

Investor read: Kirloskar Brothers Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

## Return On Capital Employed

What the numbers say: KSB Ltd leads ROCE at 24.7%, 4.3 percentage points above Kirloskar Brothers Ltd. WPIL Ltd has the strongest latest improvement at -1 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Investor read: KSB Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

Evidence: KSB Ltd · 24.7% | 21.1% versus #2 · Kirloskar Brothers Ltd | 4/8 recent comparable periods | 4/4 companies · 46 observations

Definition: ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

## Valuation Against Growth & Quality

What the numbers say: Kirloskar Brothers Ltd has the lowest comparable PEG at 1.75×, 42.2% below KSB Ltd. Only 2 of 4 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

Evidence: Kirloskar Brothers Ltd · 1.75× | 42.2% versus #2 · KSB Ltd | 0/8 recent comparable periods | 2/4 companies · 25 observations

Definition: PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

### PEG — lowest PEG
1. Kirloskar Brothers Ltd (KIRLOSBROS): 1.8
2. KSB Ltd (KSB): 3.0

### P/E — lowest P/E
1. WPIL Ltd (WPIL): 26.7
2. Kirloskar Brothers Ltd (KIRLOSBROS): 36.7
3. Roto Pumps Ltd (ROTO): 51.4
4. KSB Ltd (KSB): 54.1

## What can make this comparison misleading?
- A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
- A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
- The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
- An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
- 1 company draws at least one figure from a second data feed with too little overlapping history to cross-check against the primary source; it is marked unverified wherever that figure appears.
- 1 company is missing from the second-feed metrics by decision, not by absence: the two sources disagree, so nothing from the second is drawn. Read those rows as narrower evidence, never as a weaker business.
- Thin comparisons: Valuation have fewer than three usable current readings.

## Source standing of each company

Cross-checked: 2. Unverified: 1. Withheld: 1. Graded companies: 4.

1 of 4 companies draws at least one figure from a second data feed that could not be cross-checked against the primary source, because the two do not share enough reported history to compare. Those figures are marked unverified wherever they appear.

1 of 4 companies has a second data feed that is known to disagree with the primary source, so nothing from it is drawn: WPIL Ltd (WPIL) — its two data sources disagree by up to 24% on reported income across 14 comparable periods, so its derived ratios are withheld.

- WITHHELD | WPIL | WPIL Ltd | diff_gt_2pct | disagreement up to 23.83% over 14 comparable periods

- UNVERIFIED | ROTO | Roto Pumps Ltd | too little overlapping reported history to cross-check the second feed

## Methodology and freshness

Up to 20 quarters per company. Reported history is normalized to Indian rupees crore. Missing values are not interpolated. Derived metrics are calculated only when their inputs are comparable.

### Which Pumps company has the strongest 4-Factor Sector Score?

### Which Pumps company has the lowest comparable PEG?

Kirloskar Brothers Ltd has the lowest comparable PEG at 1.75, among 2 of 4 companies whose earnings and growth are steady enough for the ratio to mean anything.

### How much history does this Pumps comparison include?

The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Jun 2026. Missing observations remain blank rather than being estimated.

### How is the 4-Factor Sector Score calculated?

The four visible contributions add directly: growth and earnings up to 35 points, capital efficiency up to 25, valuation up to 20, and relative strength up to 20. Missing or stale evidence moves only the affected contribution toward neutral.

### What is the Nifty Pumps index?

The Nifty Pumps index tracks India's listed Pumps companies as a single basket. This page follows the same 4 companies and equal-weights them, so every company's weekly return counts once whatever it is worth, and the reading belongs to the Pumps sector rather than to its largest constituent. Figures are as of Jun 2026.

### Which are the best Pumps stocks in India?

Ranked by this page's four-factor score, WPIL Ltd places first among 4 listed Pumps companies, followed by Roto Pumps Ltd. That is a ranking of published data — earnings, quality, valuation and market behaviour as of Jun 2026 — and not a recommendation; Sector Alpha is not registered with SEBI as an investment adviser.

### How many Pumps stocks are listed in India?

This comparison covers 4 listed Pumps companies in India, each above the size floor the site applies, with 20 quarters of reported figures per company where the filings exist. The full ranked list is on this page, as of Jun 2026.

### Which Pumps company is the biggest?

Kirloskar Brothers Ltd is the largest, with trailing-twelve-month revenue of ₹4,664 crore, ahead of KSB Ltd at ₹2,702 crore. That covers 4 of 4 companies with comparable reporting through Jun 2026.

### Which Pumps company has the best profit margins?

Roto Pumps Ltd has the highest operating margin at 15.7%, from 4 of 4 comparable companies. WPIL Ltd shows the biggest recent improvement, at +2 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

### Which Pumps company makes the most profit?

Kirloskar Brothers Ltd earns the most, at ₹377 crore of trailing-twelve-month net profit, from 4 of 4 comparable companies. WPIL Ltd has the fastest profit growth at 100%, though growth off a small or recovering profit base overstates how much has actually changed.

### Which Pumps company earns the highest return on capital?

KSB Ltd leads on return on capital employed at 24.7%, across 4 of 4 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

### Which Pumps stock is the cheapest?

On PEG — where a LOWER number is cheaper — Kirloskar Brothers Ltd screens cheapest at 1.75×. Only 2 of 4 companies have earnings and growth steady enough for the ratio to mean anything, so this is not a sector-wide "cheapest stock" verdict. Cheap on a multiple is a reason to investigate, never a reason to buy on its own.

### Is the Pumps sector beating the market?

Pumps has underperformed NIFTY 500 by 10.1% over the last 52 weeks and 3.4% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 4 of 4 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

### Which Pumps stock has the strongest price momentum?

WPIL Ltd has the strongest relative strength against NIFTY 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

### Which Pumps company scores highest for research priority?

WPIL Ltd scores 61.5 out of 100 with 72.3% evidence confidence, from 22.5 points on growth and earnings, 14.2 on capital efficiency, 10 on valuation and 14.8 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

### How many Pumps companies does this comparison cover, and over what period?

It compares 4 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

### What is the total market cap of the Pumps sector?

The 4 Pumps companies on this page carry ₹35,552 crore of combined market value. KSB Ltd is the largest at ₹14,896 crore, about 42% of the sector's total on its own. Market value moves with price, so this reading is dated 2026-08-05.

### How is the Pumps sector performing?

4 of the 4 covered Pumps companies are beating NIFTY 500 on Mansfield relative strength. The sector itself is 10.1% behind NIFTY 500 over 52 weeks on an equal-weight index of its current members. Readings are as of 2026-08-05.

### Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

### Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
