WP20HCI 7hp 2inch Gasoline Cast Iron Pump

Product Overview

The WP20HCI is a 7 HP gasoline-engine cast iron pump with inlet and outlet of 50 (2") & 40(1.5"), delivering up to 30 m3/h at 40 m head and self-priming to 11 m suction. The air-cooled 4-stroke OHV single cylinder engine has a 70X55 mm bore x stroke and 212 cc of displacement, with 7.0 HP output at a compression ratio of 8.5:1. The fuel tank holds 3.6 L, the oil sump 0.6 L, and the unit measures 515X380X425, weighing 24 kg gross.

Key Features

• 30 m3/h at 40 m head: the WP20HCI moves 30 cubic metres per hour up to 40 metres of head, which is the working point to size pipe diameter and hose length against.
• 50 (2") & 40(1.5") inlet and outlet, 11 m suction lift: self-priming to 11 metres, so the pump primes from a tank, canal or shallow sump rather than needing to be flooded below the water line.
• 7 HP gasoline engine, 70X55 mm bore x stroke in 212 cc: air-cooled 4-stroke OHV single cylinder, delivering 7.0 HP at a compression ratio of 8.5:1, which is what keeps this size pumping rather than straining at the duty point.
• 3.6 L tank, 0.6 L oil, 24 kg gross, 515X380X425: starting is by recoil or electric, and the air cleaner is half-dry. One self-contained unit — no separate generator, no mains supply.

Applications

The WP20HCI is built for abrasive and gritty water where an aluminium alloy pump would wear out. It is supplied to irrigation contractors, agricultural machinery dealers, mining and construction pump builders, and water contractors who need a 7 HP gasoline driven pump. For trading companies, distributors and project buyers, WP20HCI is an economical factory-backed option with steady supply and consistent quality.

FAQ

How much flow and head does the WP20HCI deliver?

Up to 30 m3/h at 40 m total head, with 11 m maximum suction lift. Head falls as flow rises, so size the pump against the highest point you need to lift water to, and allow for friction loss in the pipe run.

Which engine is fitted, and what fuel does it run on?

A 7 HP air-cooled 4-stroke OHV single cylinder gasoline engine with 70X55 mm bore x stroke and 212 cc of displacement, giving 7.0 HP output at 8.5:1 compression ratio. It runs on gasoline, with a 3.6 L tank.

How is it started, and what servicing does it need?

Starting is by recoil or electric. The oil sump holds 0.6 L and the fuel tank 3.6 L. Prime the pump chamber with water before every start so the mechanical seal does not run dry — for a 4-stroke engine, change the oil at the interval we specify for your duty cycle.

What size is the WP20HCI, and how much does it weigh?

The bare pump measures 515X380X425 and weighs 24 kg gross. Pallet size, container loading plan and the 20ft/40HQ quantities are available on request — they depend on packing.

What kind of water is this pump suited to?

The WP20HCI is a cast iron pump intended for abrasive and gritty water where an aluminium alloy pump would wear out. The cast iron body and impeller tolerate grit and abrasive solids that would wear an aluminium alloy pump quickly.
