WP20DH 10hp 2inch Diesel High Pressure Pump

Product Overview

The WP20DH is a 10 HP diesel-engine high pressure pump with inlet and outlet of 50 (2"), delivering up to 23 m3/h at 50 m head and self-priming to 7 m suction. The single-cylinder, vertical, 4-stroke air-cooled engine has a 86X72 mm bore x stroke and 418 cc of displacement, with 10 HP output. The fuel tank holds 3.5 L, the oil sump 1.65 L, and the unit measures 600X480X600, weighing 57 kg gross.

Key Features

• 23 m3/h at 50 m head: the WP20DH moves 23 cubic metres per hour up to 50 metres of head, which is the working point to size pipe diameter and hose length against.
• 50 (2") 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.
• 10 HP diesel engine, 86X72 mm bore x stroke in 418 cc: single-cylinder, vertical, 4-stroke air-cooled, delivering 10 HP, which is what keeps this size pumping rather than straining at the duty point.
• 3.5 L tank, 1.65 L oil, 57 kg gross, 600X480X600: starting is by recoil or electric. One self-contained unit — no separate generator, no mains supply.

Applications

FAQ

How much flow and head does the WP20DH deliver?

Up to 23 m3/h at 50 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 10 HP single-cylinder, vertical, 4-stroke air-cooled diesel engine with 86X72 mm bore x stroke and 418 cc of displacement, giving 10 HP output. It runs on light diesel oil, with a 3.5 L tank.

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

Starting is by recoil or electric. The oil sump holds 1.65 L and the fuel tank 3.5 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 WP20DH, and how much does it weigh?

The bare pump measures 600X480X600 and weighs 57 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 WP20DH is a high pressure pump intended for high-pressure washing, spraying and pressure irrigation. The pressure rating suits spraying and pressure irrigation duty; it is not a high-head booster for very long vertical lifts.
