Type PH

Qmax=1400m3/h – Hmax=73m 

APPLICATION

PH pumps are used for pumping liquids containing significant amounts of solid particles (sludge). Permissible pumpage density is mainly 1700 kg/m 3 , but in individual cases, depending on the type of medium, pumping slurries of higher density is permitted at a limited rotary speed. The maximum allowable size of sold particles (passage) increases with the pump size and can reach 52 mm.

PH pumps are used in the mining industry in processing plants and enrichment of minerals, in hydraulic filling systems, hydraulic waste removal, as well as in other applications where pumping mixtures containing significant amounts of solids is required. PH-Ex pump versions are suitable for use in potentially explosive underground mines, as group I, M2 category installation.

DESIGN

PH pumps are horizontal, single stage, centrifugal pumps, with design adapted for pumping liquid mixtures and solids with abrasive properties. The inlet connection port is at the pump axis and the discharge connection port, in the basic version, is directed vertically upwards, offset laterally in relation to the pump axis.

PH pumps have closed impellers, with a small number of thickened vanes, thus increasing their life and allowing for pumping solid particles of larger size. Impellers are fitted on the front and rear discs with relieving vanes limiting the penetration of solid particles to the area of the shaft seal and the impeller neck sealing gap. This gap forms a frontal slot and its width can be adjusted with wear, without removing the pump, by moving the entire rotating assembly with Bearing housing in relation to the pump stator using special adjustment screws.

PH pumps can be made in a vertical version.

MATERIALS OF CONSTRUCTION

Standard design material version for PH pumps used in manufacturing of the flowing system is hard-wearing alloy steel casting. Cast iron is used for manufacturing bearing elements. Carbon alloy steel casting and copper-cast iron is used in manufacturing of the remaining castings.

PH pumps are also available in the following special versions:

saline-resistant steel casting version,
hot water version,
PH-Ex version designed for areas where explosion hazard is present in underground mines.
