Honda WT40 Water Pump

The Honda WT40 pumps 1640 litres a minute with 31mm debris, 2.6 bar of pressure and a 2 hours 15 minutes running time. This is a 4" trash pump, max output capacity 1600 l/min.

Debris can pass straight through.
The prime choice when handling water filled with solids, our Trash pumps are ideal for messy jobs and dirty water.

On site or at lakes and rivers, water is often dirty and filled with silt. Honda's trash pumps have been built strong to handle it. The ultimate choice for contractors or rental, our Trash pumps have been specially designed to take on the most demanding jobs. They allow gravel and other debris to flow through the pump without clogging or causing damage – all whilst pushing out professional water pumping performance. So there’s no need to worry about the water quality – just about getting the job done.

Maintaining the Trash pumps is easy.
Dealing with tough water conditions, occasionally Trash pumps can become clogged – it can happen from time to time. To solve this problem, Honda have designed a removable inspection cover that makes clearing debris quick and simple. If the pump becomes blocked , simply use the provided tool to loosen the quick-release bolts, and lift open the inspection cover to remove any debris.
Once it’s done, it’s back to work.

What makes our Trash pumps so effective is the craftsmanship of their seals – they ensure air can't be drawn in, which causes the all-important vacuum to be lost. The impeller-to-volute clearance has also been designed in this way. It all means they not only have an impressive flow rate and pressure – but they can keep it up; they can go for up to 2 hours 50 minutes before you need to add more petrol.

Heavy-duty 4" construction trash pump
Specially designed for job sites and applications where high volume trash water capacity is needed.

Easy starting Honda OHV commercial engine
The durable Honda GX series commercial grade engine is easy starting and provides ample power for the toughest conditions.

Solid handling capability up to 1 1/16"
The specially designed impeller allows solids to pass through easily, without clogging.

Heavy duty full frame protection
Protects the pump, while offering a convenient tie down location for transport.

Easy quick clean out port
The WT30 is designed for quick and easy service. An easy access service port makes clean-out quick.

Replaceable stainless steel wear plate
The volute is equipped with a replaceable stainless steel wear plate, which increases durability and reduces maintenance costs.

Standard service tool
A convenient multi-tool is provided for easy removal and installation of the pump case, for tightening and removal of the priming plug and drain plug, and for tightening and removal of the hose coupling.

Durable silicon carbide mechanical seal
Features abrasion-resistant silicone-carbide seals for extended wear.

Cast iron volute and impeller
The rigid-mount cast iron volute reduces case wear, increasing the life of the pump.

Isolation mounted engine and pump
High performance mounts minimize vibration, keeping the pump from “walking” away or “burying” itself in soft soil conditions. The reduced vibration also reduces wear on components, increasing the pump's durability.

Unique conical shaped impeller
The unique shape improves priming and higher discharge capacity. Wide vanes are designed to resist wear and maximize durability.

Protected by Honda Oil Alert®
Protects the pump by shutting the engine off when low oil is detected.
