What types of materials can a trash pump process?

Trash pumps can handle a wide variety of materials such as sand, gravel, slimy water, and even sticks and stones. The size of the debris that can be processed is determined by the size of the pump. Our range of trash pumps comes in various inlet/outlet sizes and is available in both petrol and diesel options.

What is the difference between a single and a twin impellor water pump?

The primary difference between a single impellor and a twin impellor pump is how they handle flow rate and pressure.
A single impellor water pump provides a higher flow rate at lower pressure. These models are ideal for water transfer, where large volumes need to be moved quickly, as well as moving sludge or debris-heavy water.
A twin impellor water pump delivers higher pressure at the expense of a lower flow rate. These models are best used for firefighting and long-distance water transfer.

What surfaces can be pressure washed?

Pressure washers are high-powered machines, and it is important to understand which surfaces are safe to wash without causing damage.
Surfaces that can be safely pressure washed include:

• Cement and concrete
• Most decks and patios: Most treated woods are safe to pressure wash; however, make sure to use lower pressure to avoid damage.
• Brick and stone

Surfaces that are not safe for a pressure washer:

• Delicate wood: Untreated and soft wood can be damaged by pressure washing.
• Electrical units: Although some units, such as electrical boxes, are designed to withstand rain, they are not made to withstand pressure washing, which can penetrate cracks and damage internal components.
• Engines: Much like electrical units, high-pressure water can reach interior engine components and cause damage to your engine.

Can you use a pressure washer on a car?

Yes, but do not use washers 2500 psi or over as it can damage the paint so keep the pressure to 2000 PSI or under, for high-pressure washers 2500 psi or higher, spray it with a wider spray nozzle and stand further away from the car.
