Semi-submersible centrifugal vertical sand pumps are applied for pumping of abrasive slurries (pulps) with high content of solids (up to 25%* by volume), density of pumped slurry up to 1300 kg/m³*, pH value from 6 to 8, maximum size of pumped solids not more than 10 mm and temperature of pumped slurry up to 70 °С.

TECHNICAL DATA

• Capacity range (Q): from 50 to 130 m³/h
• Head range (Н): from 10 to 60 m
• Rotation speed: 1500 rpm
• Motor power: from 2.2 to 75 KW

APPLICATIONS

Mining, metallurgy, potash industries, thermal energy (combined heat and power stations and state regional power plants), hydromechanization, oil sand processing, mining and processing of sand-and-gravel.

DESIGN

Pumps type PRVP, PKVP, PVP are centrifugal single-stage, single-casing pumps with one-side intake of slurry to impeller. Discharge pipe with flange coupling is directed vertically upwards.
