WQ Series Low-speed Electric Submersible Waste Pump HYDDBY07

Product overview

The WQ series high-lift electric submersible waste pump is manufactured as per GB/T 24674-2009 Waste submersible motor-pumps. It is of a lower pump structure, with two sets of independent bulk mechanical seals, a wear-resistant silicon carbide grinding block, a stainless steel rotating shaft, standard stainless steel exposed parts and 10 m long cables.

The 4-pole or 6-pole motor at a speed less than 1,500 rpm is installed. The outlet is provided with the flange for the purpose of flange-type connection, and it can also be configured with the pipe connector as needed by users for the purpose of flexible pipe connection. For the pump with a power greater than 30 kW, built-in protection devices for water and oil leakage, overload, over temperature, etc. are provided, and automatic electric pump startup and shutdown can be achieved via the control cabinet.
