GXV(M)25 Submersible Drainage Pumps
Calpeda GXV25 submersible drainage pumps are suitable for use in a range of applications. They come fitted with an 110v, 240v or 415v motor and can be used with or without a floatswitch. The floatswitch is quick and easy to adjust when necessary and allows the pump to be automatically stopped and started. They have a suction strainer containing a double row of holes, which helps to prevent clogging. The pumps can be used for situations involving:
- - clean or slightly dirty water, which contains solids up to 25mm in size
- - they are especially suited to the flow of liquids containing filamentous particles
The GXV pumps are manufactured from chrome-nickel stainless steel and use a single free-flow (vortex) impeller. They have a vertical delivery port, which enables them to be installed in small pits without the need for an elbow on the pump. These pumps can be used with a frequency converter. The pumped water passes between the motor jacket and the external jacket to help cool the motor. The double shaft seal with oil chamber keeps the motor separate from the water and prevents accidental use when it is dry.
The GXV25 range of submersible drainage pumps have a maximum flow rate of 220 litres per minute and can accommodate heads up to 12.7m. They are suitable for use with liquid temperatures up to 50C. The pumps can be immersed up to a maximum depth of 5m. When they're used with a floatswitch, the minimum water level should be 130mm. For manually operated pumps the minimum level is 30mm.
