SIDE CHANNEL CENTRIFUGAL PUMPS
For drinking water and industrial purposes, for sea water, for automatic system with hydrophore tank, for conveying acid and alcaline liquids, petrol and light oils, for condensate and liquid with vapours, for food and pharmaceutical products.
BT pumps are self-priming side channel multistage pumps. The impellers are star shaped, hydraulically balanced to reduce axial thrust on the bearings. Bearings are external, life grease lubricated. The pumps have a very low NPSHr value that allows operation with suction lift up to 8 meters. Their working principle makes these pumps particularly suitable to transfer liquid gas/vapour mixtures. Basic design pumps are mechanically sealed. It is possible to fit double mechanical seals when handling hot liquids which may solidify, toxic, aggressive and corrosive media. In this case the seals are flushed from an external source with a fluid compatible with pumped medium at a slightly higher pressure.
