High Efficiency Pressure Diesel Engine Centrifugal Fire Protection Pump

Introduction
This series of pump is of sub-horizontal, multi-stage single-suction and centrifugal, using state-recommended hydromodule. The  pump is efficient, reliable, and durable with low noise performance, easy maintenance and wide scope of usage. Our pump is applicable to deliver those fluid without solid, particles or any other suspended stuff, water for instance. While oil and corrosive or solid-contained fulid can be pumped by means of material modification, sealing methods, and cooling system adding.

Features
1.High Efficiency and Energy saving 
 We have developed our unique technology for manufacturing, model designing and making, foundry techniques of hydraulic parts to assure their brightness, cleanliness, and accurate dimensions. So the actual efficiency are at least 2% higher than other general multistage centrifugal pumps
2Advanced process equipment 
Every single processed part will have cleaned by means of advanced imported   cleaning equipment for better assembling concern. Besides material inspection, hydraulic test, static balancing testing, all pump rotors beyond 6 grades will have axial movement tested controlled within 5 millisecond, and then the balancing test shall be made according to G2.5 grade. Recheck axial movement of all shafts after assembly to assure the quality of the pump.
3.Unique structure
A sealing 0-ring is set between balancing ring and fitting surface of the pump to avoid high pressure water coming into balancing stage and wear and tear of the balabcing plate to obtain better durability,
4.Material choosing
Balancing plate and the eara around can be made of welding alloy,alloy steel or ductile cast iron QT600Mn2 concerning their high surficial hardness and fine durability, Flowing-over part of MD pump is of abrasion resistant by using material of alloy wear resistant ductile cast iron or high-grade wear-resistant ductile cast iron.
5.Fine appearance
The appearance of the pump is fine taking advantage of precise mold casting procedures and automatic painting.
