This series of pumps are horizontal multi-stage sectional centrifugal pump, the country is recommended to use the hydraulic model of high efficiency and energy saving products, with high efficiency, wide range of performance, safe operation, convenient maintenance, etc.

This series of pump for conveying ≦ 1.5% solids content, particle ≦ 0.5 mm, the temperature is below 80 ℃ of neutral mine water and sewage, similar to other pump allows the inlet pressure of not more than 0.6 MPa. Suitable for mines, factories and urban water supply and drainage engineering. This series of multistage centrifugal pump, factory direct sale, welcome customers to inquire order.

The D type pump is horizontal, single-stage, sectional multi-stage centrifugal pump, the suction for the horizontal direction, spit export for vertical upward. The pump inlet section, the middle part, as well as the water pump shell by tension bolt connection into an organic whole, and choose according to pump lift pump series.

This series of pump rotor parts is mainly composed of shaft and installed on the shaft of the impeller, shaft sleeve, balance disc and other parts, including the number of impeller, according to the series of the pump shaft parts through the key and the shaft nut hard to that of the shaft etc. The rotor by the rolling bearing and sliding bearing on both ends. Bearing according to the different models, are not under axial force, and the axial force by the balancing disc, and installed on the pump end balance disc wear indicator, to monitor the balance disc wear.

Pump inlet section, middle/water sealing surface adopt sealant or "O" ring seal and the rotor part and fixed part between a seal and guide vane, etc, when the seal ring and the degree of wear of guide vane set had influence on the performance of the pump work shall be replaced in a timely manner.

Shaft seal form of mechanical seals and packing seal, pump using packing seal, positioning of correct packing ring, packing tightness must be appropriate, with liquid can drip seeps advisable. Loading pump seal element in a sealed cavity, cavity access to certain pressure of water, the water seal, the action of water, or water lubrication, fitted with replaceable shaft sleeve in shaft seal place, in order to protect the pump shaft.

Allows the rotor in the operation of the pump in the pump shell axial float, this type of pump is generally adopts rolling bearing, the structure of the centralized grease lubrication (D85-67, D155-67 type pump can adopt sliding bearing, thin oil lubrication structure, also can use rolling bearing, dry oil lubricating structure).

This series of pump through flexible coupling driven directly by the prime mover. From the direction of the prime mover, pump is clockwise.
