WA1 & WA1R Serie

General:
　　Type WA1 & WA1R pumps are used for pumping clean water or liquids which are similar to clearn water in properties of physics and chemistry.The temperatures of Type is pump must not more than 80^oC. Type WA1R pumpscan convery hot water not more than 130^oC. The pumps are suitable for industrial and municipal water supply and drainage and are adapted for agricultural irrigation.
Performance Range (series of the pump)
Capacities: Q 6.3m³m/h~400m³/h
Heads: H 5m~124m
Allowed suction pressure≤0.6Mpa(the pressure value should be indicated in order)

◆ Construction:
Type is & WA1R pumps are single-stage, single suction centrifugal pumps (and suction). The performance and size are desiganed according to the standard ISO 2858. Pump casing and cover of type WA1 pump are radially split at the back side of the impeller. This construction is convenient for maintenance. A spacer coupling permits to inspect the rotor without disturbing pump casing. Suction and discharge pipelines and motor.

◆ Shaft sealing:
Type is pump adopt soft-packed stuffing sealing in region of shaft sealing, the shaft is protected with renewable sleeve.
Type WA1R pump adopt soft-packed stuffing sealing and mechanical sealing.

◆ Drive:
The pumps are driven by motor through a flexible spacer coupling or a longer one. Rotation of pump is clockwise viewed from direction of motor.

◆ Balancing devlce:
To balancing the thruat, wear rings are designed on the front and back of impeller. The balancing holes are drilled in the back shroud of impeller.

◆ Material:
Pump casing ……………Cast iron
Pump cover ………………Cast iron
Shaft ……………………… Fine carbon steel
Impeller ………………… Cast iron
