GD 60-2

GD 60-2 pumps are API674/675 positive displacement piston or diaphragm pumps for the dosing and injection of fluids.

  •             Output: up to 11,400 l/h per head, at 9 bar.                                          
  •             Pressures: up to 159 bar, for 700 l/h per head.
  •             Output capacity doubled by dual-action head.
  •             Flow adjustable from 0 to 100 % while running or stopped.
  •             Maximum stroke length: 60 mm.
  •             Maximum thrust: 2000 daN.
  •             Maximum motor rating: 15 KW.

Mechanical reliability of the GD 60-2 pumps is ensured by the limited number of moving parts, which are generously sized. Readily accessible, these components are installed in dust- and splashproof housing for reduced maintenance costs.

The wheel/screw pair driven by the motor actuates the con rod/crank system via an eccentric. The piston-carrier, attached to the pumping beam, performs an alternating linear movement. The operating rate depends on the rotational speed of the motor and the reduction torque ratio. The motor is mounted on an elastic coupling.

Flow Adjustment:

The flow rate of the GD 60-2 pumps is adjustable manually as standard by micrometric screw with a sealed dial graduated from 0 to 100 % of the maximum stroke. The adjustment is made by variation of the piston stroke. Accuracy is better than 1 % from 10 to 100 % of maximum output.

Control System:

  • Pneumatic servomotors adjust output from 0 to 100 % according to the air pressure of the control signal, from 3 to 15 psig. Air is supplied to the cylinder at 4 to 7 bar.
  • Two-way servomotors powered at 230/400 V 50 Hz with manual or automatic control. The control signals may be 4-20 mA or 0-10 V.
  • Other options available: electropneumatic converters, variable frequency motors.


From 2 to 7 GD 60-2 plunger piston or diaphragm pump drive mechanisms may be combined.

Dosing Heads:

The GD 60-2 pump may be fitted with two types of dosing head:

– Plunger piston dosing head: for neutral products or for pressures of up to 440 bar.

– Diaphragm dosing head: complete tightness, safety, total protection.
