QBY pneumatic diaphragm pump
QBY pneumatic diaphragm pump does not need to be irrigated with water, the flow of the wide sheltered, allowing the passage of both the pumping of flowing liquids, but also to transport some of the media is not easy to flow with a self-absorbing pumps, submersible pumps, shielding pumps, slurry pumps and impurities pumps, and so on, has many advantages. Can be submerged in the medium work, this pump does not need to use oil lubrication, even if idling, the pump does not have any effect. The head and flow rate can be steplessly adjusted by the opening of air valve. The standard suction range is up to 7m, the head is up to 50m, and the outlet pressure is ≥6kgf/c㎡.
Shangcheng sludge screw pump
Sludge screw pump that is a single screw pump, its main working part is the eccentric helix of the screw (i.e., rotor) and the inner surface of the screw bushing (i.e., stator) with a bilinear helical surface The sludge screw pump is a single-screw type transport pump, its main working part is the eccentric helix of the screw (called the rotor) and the inner surface of the screw bush with a bilinear helical surface (called the stator). stator). The working principle is when the motor drives the pump shaft rotation, screw on the one hand around its own axis of rotation, on the other hand, it is rolling along the inner surface of the bushing, so the formation of the pump sealing chamber. Screw every turn a week, the liquid in the sealing chamber forward a pitch, with the continuous rotation of the screw, the liquid spiral way from a sealing chamber to another sealing chamber, and finally extruded from the pump body. Screw pump is a new type of machinery to transport liquid, with simple structure, safe and reliable work, easy to use and maintain, continuous and uniform liquid discharge, stable pressure and other advantages.
ZW self-priming sewage pump
ZW self-priming sewage pump is developed by our designers according to the structure and performance of ZX-type self-priming centrifugal pump and QW-type sewage pump, drawing on the advantages of similar products at home and abroad, and absorbing the requirements of the majority of users and the comments made by the use of a wide range of aspects of the development of a collection of self-priming and sewage in one, not only as a general clear-water pumps without the need for bottom valves, without irrigation and diversion, but also to pump the water. Need to irrigation and diversion of water, but also can be pumped containing large particles of solid diameter of 60% of the outlet diameter and fiber length for the impeller diameter of 1.5 times the dirt, sediment, waste impurities, fecal matter and all engineering sewage and gelatinous liquids, completely reduce the labor intensity of the workers, and the use of mobile, easy to install, very little maintenance, stable performance.
WQP stainless steel submersible sewage pump adopts the design of large flow channel anti-clogging hydraulic parts, greatly improving the dirt passing capacity, can effectively pass the pump caliber of 5 times the fibrous material and the diameter of the pump caliber of about 50% of the solid particles. Reasonable design, reasonable supporting motor, high efficiency, energy saving effect is remarkable. Mechanical seal adopts double-channel tandem seal, the material is hard wear-resistant tungsten carbide, durable, wear-resistant and so on, which can make the pump safe and continuous operation for more than 8000 hours
