China factory price diesel energy fire fighting pump

QS serie fire pump is mainly used for fire protection system pressurized water supply in pipeline. They are also used for industrial and urban water supply and discharge, pressurized water supply in high-rise constructions, distant distance water delivery, heating, bathrooms and boilers, cold and hot water circulation pressurization air conditioning refrigeration system water delivery, and used to match other equipments.

QS serie single suction single stage fire pump is composed of motor and pump of two parts, the pump and motor coaxial, pump structure including pump body, impeller, pump cover, mechanical seal, etc. Parts. The inlet and outlet of the pump in the same horizontal axis, and caliber same specification, loading and unloading is extremely convenient, cover an area of an area small. Pump has installed base, ease of installation, increase the pump running stability. Pump seal use of mechanical seal, with reliable sealing, no leakage characteristics. The axial force of pump impeller by a balance ring to balance. The import and export of the pump flange to press 1.6 MPa, line matching convenient.
QS serie single-suction multi-stage sectional fire pump is composed of motor and pump two parts, motor as Y three-phase asynchronous motor, pump and motor using coupling joint, the overall for rigid connection, use without correction. Pump stator and rotor part by part. Pump stator parts by water section, the middle, guide vane and outlet section, stuffing box body, and other integral parts. To prevent stator wear, the stator with sealing ring, balance set, after wear available spare parts replacement. Rotor part by shaft, wheel, balance drum, etc. Rotor bottom water lubrication bearing, upside for angular contact ball bearing, pump axial force most by balancing drum to take, the rest of the small residual shaft downward force by angular contact ball bearing to bear. The middle section, water and water section of the joint surface paper pad through the tension to seal, user can choose according to need.

This series pump comply with the standards of GB/T3 216 and GB/T5657.
