★Structure
The upper exhaust passage at center of pump body can prevent air block. A double volute casing reduces radial forces and shaft deflection. Gap dimension between impeller and wearing plate can be adjusted from outside in order to retain constant gap dimension and to maintain continuous high efficiency of pump operation. Open impeller, close impeller or special open impeller can be selected depend on different operation conditions. Impeller is fixed with rotor key in order to obtain a reliable and stable operation. Rotor key is self-locking and reverse rotation safe and enables an easy and quick dismantling and assembly of impeller.
