Description:

· Handheld Hydraulic submersible pumps are used when pumping clean or sewage water or various slurry on building sites, in flooded excavations, in cellars and in wells etc.

· They are commonly used in municipal and rescue applications where reliability and performance are critical.

· Hydraulic submersible pumps are designed for the high demands in the construction industry. The clever impeller design of the pump ensures that the pump is unaffected of particles size up to 74 mm.
· The impeller at top sets the water in a circular movement and by centrifugal force a centre of air shaped like a cone will occur.

· This way there is very little contact between the water and the impeller, and wear is greatly reduced compared to other types of pumps.

· The pumps have a very big capacity – up to 180 m³/h. Can be connected to power packs or excavators, trucks, tractors, etc.

· Hydraulic driven motor are cooled and lubricated in the hydraulic oil. It can run dry without any damage, unlike electric pumps

Advantage:

1. Greater suction power

Compared with the municipal dredging and sewage suction trucks that relies on vacuum suction, the hydraulically driven slurry pump has higher effiency, stronger kinetic energy and greater suction power.

2. Safe

Handheld hydraulic submersible pump doesn’t use electricity, there will be no leakage. Even if someone works with the slurry pump at the same time under the water, will not worry about leakage.

3. Discharged particulate matter

The pump impeller is not an ordinary propeller type impeller, but two independent tile type impellers surround each other. The gap in the middle is large, and larger particles can be passed through. As long as the sundries can be sucked in, and be discharged basically by the slurry pump. This advantage is especially obvious in municipal sewage, septic tank extraction.

4. Allow run empty

Because the power is from the hydraulic power station with hydraulic oil radiator. Even if the pump runs empty, if will not burn the slurry pump due to overheating.

5. Good explosion-proof

hydraulic submersible pump can work in underground pipeline mathane, flammable and explosive environment.

6. Resistance corrosion

The impeller is made of cast iron material, So the pump can be used for several years in normal without being corroded. Especially impeller, ordinary water pump with resin impeller which corrosion in case of corrosive sewage, not suitable for the sewage of excessive acid or alkali. And slurry pump(mud pump) can operate freely.
