Motor Pump Groups Series SMG and MMG

hp motor pump groups series SMG and MMG

NOTE Can be combined with a normal coupling or magnetic coupling.

For the motor pump groups, horizontal single units are combined with industrial pumps and shaft mechanical seal (SMG) or magnetic coupling (MMG) and can be loaded up to max. 5 bar and max. 150 ° C. Easy to operate, maximum operational safety, extremely low-noise, high suction power and long service life.

When used as feed units for fuel oil supply to DIN/EN 12514-1, the max. operating pressure of 6 bar must not be exceeded.

Details and applications:

  • as conveying or feed units, designed for up to 9 bar pressure
  • as pressure units, designed for up to 30 bar pressure
  • with higher pressures, suitable for up to 40 bar
  • The pump units are fitted with standard rotary current motors B3/B14 or B3/B5, 230 V, 400 V, 50 Hz, 1400 RPM, Protection IP 55, insulation class F
  • From 4 kW the motors are executed for 400/690 V, 50 Hz
  • Y-∆-cirquit with power supply must be specified with orders
  • Other voltages and frequencies can be supplied at an additional cost
  • Installation situation: Horizontal, connections upwards
