QNP Series Submersible Sludge Pump

QNP series submersible mud pump

QNP series submersible mud pump is designed to meet the needs of sand pumping and land reclamation in coastal areas, sand suction and silt removal in water conservancy dredging projects, and extraction of high-concentration fluid media containing solid particles in modern power, metallurgy, coal, mining, and construction industries. Based on the company's nearly 50 years of experience in designing and manufacturing various types of water pump products, it cooperates with Tsinghua University, widely draws on and absorbs advanced domestic and foreign technological achievements, and adopts two-phase flow theory to develop a new generation of energy-saving and wear-resistant series of submersible mud pump products with world-leading level. This series of pumps allows the pumping of solid particles with a diameter of up to 50mm, a solid-liquid mixture volume concentration of 45, and a medium temperature of 45℃. The flow range of the series products: 50-400m*/h, and the head range: 26-50m.

Product advantages

With a sand agitator in front of the suction port

When operating underwater, it can automatically stir up the mud and sand, without the need to configure hydraulic or other forms of sand agitation devices, which simplifies the structure of the sand pumping system, reduces the weight, and saves the investment in auxiliary devices and its power consumption.

The sealing structure of the pump is advanced and reliable

Adopting power: mechanical combination shaft type special mechanical seal

Perfect and reliable automatic protection function

The motor protection system of the pump adopts automatic leakage detection, electronic temperature automatic protection and motor water inlet electronic detection technology, which can dynamically monitor and protect the working state of the motor in real time, and can immediately respond to abnormal conditions to avoid safety accidents and failures.

Adopting intelligent soft start system controlled by single-chip microcomputer

The startup parameters can be set as needed to meet the different needs of users; at the same time, it can avoid the impact of startup acceleration shock on the machine parts and extend the life of the pump unit. According to user needs, variable frequency speed regulation system can also be selected

Special floating platform is available

The upper pump water entry and lifting motor device and the special machine room for pump operators on duty are available for users to choose

For occasions where long-distance loosening is required

A long-distance sand transport system is available for users to choose
