PUMP INSTALLATION AND APPLICATIONS

VXI pumps are designed to lift dirty water which is not chemically aggressive to the pump components. Their construction makes them particularly suitable for DOMESTIC, CIVIL AND INDUSTRIAL applications, in all cases where suspended solids up to Ø 50mm have to be dealt with, such as water mixed with mud, groundwater and surface water.

RECOMMENDED APPLICATIONS INCLUDE DRAINING FLOODED AREAS SUCH AS BASEMENTS AND GARAGES, UNDERGROUND CAR PARKS, WASHING AREAS FOR MACHINERY, PUMPING DOMESTIC WASTE, EMPTYING CESSPITS, AND THE DISPOSAL OF SEWAGE, DIRTY AND WASTE WATER.

These pumps are easy to install and dependable when used in fixed automatic installations.

A purpose built sump is recommended for fixed installations (minimum dimensions 500 x 500 x 500 mm) to provide total drainage and allow correct operation of the float switch. The adjustable float switch is supplied as standard on single phase models and automatically starts the pump when the fluid reaches a preset level, stopping it once the fluid has been emptied.

Installing a suitable non- return valve on the delivery pipe prevents reverse flow when the pump stops.
