 Download the file of documents. Format:* .PDF

Design:

Three-screw pumps of A1 (A2, A3 and other modifications) 3V type are designed to pump non-aggressive liquids having a lubricating power, without abrasive mechanical impurities and with a viscosity of up to 1500 сSt and a temperature of up to 100°C (at the Customer's request up to 150°C). The lower limit of viscosity is restricted by lubricating power of the liquid being handled the upper limit - by power of electric motor and absorbing ability of the pump.

Conventional designation:


For example:
A 1 3V 125/16-90/6,3 B-2 TY26-06-1546-89

A - design code of the pump
1 - version
3V 125/16 - designation of pump as per GOST20883
90 - capacity of pump when coupled with motor, m3/h
6,3 - pressure of pump when coupled with motor, kgf/cm2
B - material of flow passage - bronze
2 - version of motor
TY 26-06-1546-89 - designation of technical specifications


Conventional designation adopted for characteristic curves:
Q - capacity, m3/h;
P - pressure of pump when coupled with motor, kgf/cm2;
N - power of electric motor, kW;
n - frequency of rotation, rpm;
 - efficiency, %;;
- vacuummetric suction lift, m;;
