Operation scope

Designation of type

DP series horizontal multistage centrifugal pump is a single suction and self-balance pump, this series is the best instead product of D series horizontal multistage pump. DP series products with a wide high-efficiency scope, good NPSH performance, smoothly operation, less wearing parts, high stable and low cost of maintain.With S is of the first-stage double-suction structure, which with better NPSH performance.The product strict implementation of standards GB/T5657 "Centrifugal pump condition classIII standard",MT/T114-2005 "Multistage centrifugal pump for mine", GB/T3216"Rotodynamic pumps -- Hydraulic performance acceptance tests -- Grades 2".

DP Type: Used for the delivery of water or physical and chemical properties similar to liquid water

the rational use of pump materials according to different media.

Reliable and secure architecture: a symmetrical arrangement of the impeller rotor assembly, the axial force impeller cancel each other, without the need for a balance disc structure can achieve self-balancing axial force of the pump, residual axial force by a pair of angular contact ball bearings bear;New technology: new throttled device while reducing leakage and improve efficiency; Further support can play a supporting role in the safe and stable operation of the pump;Seal reliable: balanced structure makes mechanical seal chamber packing chamber without excessive pressure, prolong life;Good anti-cavitation performance: a good first stage impeller cavitation performance, and excellent first-stage double suction impeller, coupled with reliable material, so that the pump can be applied in a variety of NPSH demanding situations;Mechanical seal reliable: pump rotor axial movement does not exist to solve the poor multistage pump mechanical seal reliability problems;Low-maintenance: the abolition of failure-prone balance disc structure, greatly improved reliability, reduced maintenance frequency, low maintenance costs;High efficiency: impeller and guide vane for the good performance, and will not appear balance disc wear, rotor efficiency drop phenomenon occurs forward;Adapts to various media: by replacing the material, you can transport solid particles, oil, corrosive medium containing.

In the first stage impeller rotor mounted on the shaft, impeller, throttle gear sets, anti impeller, bushings and other parts; pump "for a fixed period, for some swimming" greased structure, drive end using cylindrical roller bearing, non-drive using a pair of angular contact ball bearings to the residual axial force; and a pair of angular contact ball bearings mounted opposite.

Suction section of the pump, middle, sealed with sealant between the water segment, with sealing ring between the rotor and the fixed portion, the vane seal ring seal, when the seal ring wear to be replaced should affect pump performance;

There are two types of axis seal: mechanical seal and packing seal

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