WP30S 7hp 3inch Gasoline Trash Pump

Product Overview

The WP30S is a 7 HP gasoline-engine trash pump with inlet and outlet of 80 (3"), delivering up to 60 m3/h at 26 m head and self-priming to 7 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 545X460X44.5, weighing 31 kg gross.

Key Features

• 60 m3/h at 26 m head: the WP30S moves 60 cubic metres per hour up to 26 metres of head, which is the working point to size pipe diameter and hose length against.
• 80 (3") inlet and outlet, 7 m suction lift: self-priming to 7 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, 31 kg gross, 545X460X44.5: starting is by recoil or electric, and the air cleaner is half-dry. One self-contained unit — no separate generator, no mains supply.

FAQ

How much flow and head does the WP30S deliver?

Up to 60 m3/h at 26 m total head, with 7 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 WP30S, and how much does it weigh?

The bare pump measures 545X460X44.5 and weighs 31 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 WP30S is a trash pump intended for silty water, irrigation canal cleaning and pond draining. The wear parts are built for water carrying solids; passing larger debris will still damage the impeller.
