V Pumps are submersible vortex pump for dirty water, designed mainly for domestic use and industrial use. Their operating principle is that of a centrifugal pump with a retracted vortex impeller. A large size ring chamber with a threaded delivery opening is machined in the pump body and closed by a cover, housing the suction opening, which is shaped to prevent suspended solids over a certain size from entering the pump. Since the impeller is retracted with respect to the cover, water entering the front chamber lying between these two components assumes a vortex motion and is centrifuged in to the ring chamber leaving the pump via the delivery opening.
Pump Installation and Application
V pumps are designed to lift dirty water which is not chemically aggressive to the pump components. In all cases where suspended solids up to 35mm have to be dealt with. Recommended applications therefore include draining flooding in confined areas such as basements and garages also pumping domestic waste and the disposal of waste water containing fibers matter and are also widely used in many factories. These pumps are easy to install and dependable when used automatically in fixed installations. This system with float switch automatically starts the pump when the fluid reaches a pressure 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.
