Bwq Series Submersible Sewage Pump from 0.75kw to 280 kw
[Overview]
♦BWQ series submersible sewage pump is based on WQ to absorb the advanced technology and advantages of similar products at home and abroad, using the best hydraulic model, special structure and materials, combined with the characteristics of sewage and the actual needs of sewage discharge and the development of the most advanced third-generation new sewage pump at home and abroad, its efficiency and performance are better than domestic and foreign products.
♦The pump has the remarkable characteristics of high efficiency and energy saving, no clogging, anti-winding, long life, etc., and can be equipped with automatic coupling installation
♦BWQ series submersible sewage pumps are mainly used in municipal engineering, industry, hospitals, construction, hotels, restaurants and other industries to discharge sludge, waste water and urban domestic water with solid particles and various long fibers (including corrosive and corrosive media).
♦The temperature of the medium does not exceed 40°C, and the density of the medium < 1050kg/m³
♦The pH value is in the range of 5~9.
♦The rated voltage is 380V+5%, and the rated frequency is 50HZ.
♦There are no soft entanglements and solid objects exceeding the suction permit of the submersible sewage pump in the working waters, so as to prevent sediment from blocking the inlet of the pump, ensure smooth suction and ensure the vertical installation of the pump; Meet the minimum submerged depth of the pump.
[Performance Parameter Range]
♦Caliber: DN40~DN600
♦Supporting power: 0.75~280kW
♦Flow rate: 10m³/h~5000m³/h
♦Head: 7m~40m
♦Speed: 740, 980, 1480, 2900r/min
[Features & Benefits]
1. The unique double-channel impeller design, the best matching pump body, has the characteristics of no clogging, anti-winding, high efficiency, good balance, etc., and is most suitable for discharging and containing solids
bulk particles and long fibers of sewage, waste water and rainwater, etc.
2. The motor specially designed for sewage has a protection level of IP68, F-class insulation, and an overheating protection element embedded in the winding, which protects the motor through the electric control cabinet
3. The submersible motor relies on the liquid being pumped for cooling, and the lowest operating water level must be in the upper part of the stator shell of the motor.
4. The pump is equipped with two independent mechanical seals to achieve the purpose of double sealing. The lubricating oil in the oil chamber not only lubricates the mechanical seals, but also prevents the penetration of the medium.
5. The pump is equipped with a water leakage probe, overheating protection element and float switch, which can automatically monitor the water leakage, oil leakage and winding overheating of the pump when combined with the special electric control cabinet.
A special bearing temperature protection monitoring system is set up in the bearing chamber (the pump is not configured under normal factory conditions, please specify it when ordering).
