Three -screw vertical type pumps A1 (A2, A3 and other modifications) are 3V to pump non -aggressive fluids with lubricating ability, without abrasive mechanical impurities, viscosity up to 1,500 STOs and a temperature of up to 100 ° C (as agreed with the manufacturer up to 150 ° C). The lower viscosity limit is limited to the lubricant of the pumped liquid, the upper one with the power of the electric motor and the absorption of the pump. When ordering the limits of viscosity and the operating temperature of the pumped fluid, it is necessary to stipulate.
three -screw pumps for oil products A1 3B, A2 3V, A3 3V are made for installation in technological lines for supplying fuel and pumping oil products ( General -industrial pumps ). Three -screw pumps are characterized by high indicators of reliability, economy, low noise when working on pure mineral oils (high -pressure hydraulics pumps).
