The HP-OHH is developed as radial split, single- stage overhung cantilever pump, which comply with the requirements of API610 and ISO13709.The pump is effective where pressure or temperature is high. It has some unique design in hydraulic design and construction. The bearing has low temperature rise, low vibration, long service life and high reliability under high inlet pressure. The HP-OHH pumps modular construction system offers wide ranging interchangeability of components such as shafts, casings, covers, wear rings, shaft seals and bearings among the various pump ranges.
