Our sump pumps are of the centrifugal type, pumping fluid by means of an air driven impeller. The pump should be immersed in the liquid to be pumped. The liquid will leave the pump through the outlet port. These pumps are designed for high performance and durability.
Both models will pump down to within only (22 mm) from the base. They require no priming and can be run continuously, or even run dry, without overheating. They can be totally submerged, using a non-return valve on the exhaust pipe or an extended pipe ending above the level of the liquid.
The pumps can be used in places where abuse and rough use are inevitable or acceptable in terms of increase in productivity. They are relatively small in size with a very large capacity and thus can be used in confined spaces.
Our sludge pump operates by filling the pump chamber with liquid by means of a venturi arrangement, where compressed air is forced through a restriction in the top part of the pump head, creating an under pressure within the pump chamber. The pumped liquid is then sucked into the pump hamber through an inlet valve. When the chamber is full, this triggers a valve, pressurizing the filled pump chamber. The contents of the chamber are then pressed out through the outlet port.
Our sludge pump may be operated partly submerged. It can also be used for limited suction applications, since it doesn’t need to be immersed in the liquid.
