  • Page 2 MUST How the pump works NETZSCH Progressing Cavity Pumps operate at a constant torque requirement for a specific operating pressure. The speed of the pump does NOT affect the torque requirement. For example: a pump running at 60psi output pressure at a speed of 200 revolutions per minute requires the same toque input as if it were running at 60psi output pressure at a speed of 600 revolutions per minute.
  • Page 3 NETZSCH Pumps North America, LLC has an overload capacity of the VFD's full load ampere rating times 110% - 120% for one minute and Heavy Duty; which has an overload capacity of the VFD's full load ampere rating times 150% for one minute. Typically, constant Hp VFD’s are sold with a Normal duty rating since the applications don’t call for high starting torque which causes amp draw to spike.

    Fill the piping on the pump suction side. In anti–clockwise rotation only: Fill the pump housing. The NEMO ® pump is a progressing cavity pump which can produce pressures that may cause the bursting of vessels or pipes. The power transmission train (shaft, coupling rod, joints, rotor) of the pump may be overloaded thus resulting in damage or breakage.
