Product Description
PBWH stainless steel horizontal pumps are shielded by the pump motor to form a seal and shielding whole , the overall use of static seal design . Can be widely used in heating, sanitary water , chilled water system, hot and cold water transport non-corrosive , it is hotels, hospitals , factories, and other high-end residential heat exchange station , ideal for central heating pipes conveying equipment . It has in common than horizontal centrifugal pumps, compact machine integrated structure , small size , beautiful appearance , smooth operation , easy installation , no noise , zero leakage , etc. , and satisfy the growing user work environment stability and environmental requirements.
Features Uses
Shield centrifugal pump has a compact machine integrated structure , small size , beautiful appearance , smooth operation , easy installation , no noise , no leakage , no pollution. Widely used in HVAC air conditioning and hot water , industrial, urban domestic water , pipeline booster , long-distance water and other occasions , transform materials derived products more suitable for petroleum, chemical , pharmaceutical, food , refrigeration and so on. High and low temperature , high pressure on various occasions .
Working conditions
1, Power rated voltage of 380V, frequency of 50Hz, three-phase AC ;
2, transmission fluid at a volume ratio of not more than 0.1% and particle size of the solid particles greater than 0.2mm ;
3 , transmission fluid temperature of ≤ 120 ℃;
4, the system pressure does not exceed 1.0MPa, not less than 50Kpa; If more than please specify when ordering ;
5 , the ambient temperature does not exceed 40 ℃;

Structure Description
This product is a horizontal centrifugal pump consists of two parts pumps and shielded motor ( hereinafter referred to as the motor ) . Some of the major components of the impeller pump , pump, seal ring, the motor part of the main components of the stator , rotor, shielding sleeve , bearing , bearings, thrust plate , cooling , air release valve and other component parts .
Class H insulation winding motor selection . The rotor shaft made of stainless steel and cast aluminum rotor components. In order to prevent corrosion of transmission fluid into the stator and the rotor , the inner diameter of the stator and the rotor surface are made of stainless steel shielding sleeve seal.
Sealing: pump flange and the motor flange connection , frame and bearing and the stator heat shield connections are O -ring seal. Cantilever pump impeller mounted on the motor shaft, to be secured by a bond and nuts.
Lubrication and cooling : The outer loop . When the pump is working , at the outlet of the pump leads to a small amount of liquid through the cooling tube , the gap between the bearing and journal , stator and rotor gap , the gap before the bearing and journal , the impeller ring form a circulation loop port ( single-stage ) , and finally an impeller inlet ring composed of a circulating loop ( multi-level ) .
