HDSE250-35 hydraulic submersible sand pump for Volvo EC240 excavator

HDSE submersible sand dredging pump is hydraulic machinery, the motor and the pump of which are coaxially working submerged in medium . The wetted parts of the pump are made of high chromium wearable alloy , so the pump has good wear resistance and large flowing passage. It is applicable for conveying medium such as sludge, ore slurry, coal slurry, sand stones containing big solid particles.

The hydraulic station wear resistant slurry pump and heavy duty submersible sand dredging

pump manufactured by our company are suitable for small portable station or 120, 150, 220, 240, 300, 330, 360 and other small, middle and large excavators. In case of much water, thin sludge and sediment, inconvenient digging with the digging bucket, remove the digging bucket, connect the hydraulic mortar pump, and conduct high-efficient extraction with high concentration. The hydraulic slurry pump is allocated, which realizes long distance transmission. The hydraulic slurry pump greatly improves working efficiency.

Structure Features:

 1. The pump bottom is arranged with the mixing device, and the bilateral and multilateral

separate mixer can be arranged, which can prevent pump blockage by the bulky fixed substance, so as to fully mix the solid with liquid, and facilitate handling.

2. The pump can handle the solid substance with the maximum particle size of 150mm, and the solid-liquid extraction concentration can be over 70%;

3. The device is mainly installed on the excavator, and the power is provided by the hydraulic station of the excavator, which can realize free transition.

The power source is diesel engine, which can solve the problem of power inconvenience during construction in the remote area.

4. Wetted parts: i.e., pump shell, impeller, guard board and mixing impeller adopt the high-chromium alloy. Other materials can be customized.

5. The unique sealing device is adopted, so as to avoid frequent replacement of mechanical seal, and improve the working efficiency.
