Super K

SUPER K pumps are API 674/675 positive displacement piston or diaphragm pumps for the dosing and injection of fluids.

  • Output: up to 50 l/h, at 159 bar
  • Pressures: up to 440 bar for 18 l/h
  • Flow adjustable from 0 to 100 % while running or stopped
  • Maximum stroke length: 21 mm
  • Maximum thrust: 500 daN
  • Maximum motor rating: 1.1 kW

The mechanical reliability of the Super K 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:

In the standard version, adjustment is manual by a micrometer screw. Flow adjustment is obtained by setting-over, and modification of piston-shaft stroke. This is done by changing the position of setting screw and push rod. Eccentric axle position is modified by push rod oblique slot. Flow adjustment may be set while running or motor stopped. Accuracy is better than 1 % from 10 to 100 % of maximum output.


  • The Super J pumps are driven by an electric actuator powered in both directions, adjusting output between 0 to 100 % depending on the air pressure of the control signal, from 3 to 15 psig and supplied by 230V / 400 Vac at 50 Hz, with automatic or manual control system.
  • The air supply cylinder is made under 4 to 7 bar and the command signal may be 4_20mA or 0-10V.
  • Other options are available with electropneumatic converters and variable frequency motors.


From 2 to 7 Super K plunger piston or diaphragm pump drive mechanisms may be combined.

Dosing Heads:

The Super K pump may be fitted with two types of dosing head:

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

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