Super KL

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

  • Output: up to 4000 l/h à 4 bar
  • Pressures: up to 440 bar for 37 l/h
  • Flow adjustable from 0 to 100 % while running or stopped
  • Maximum stroke length: 40 mm
  • Maximum thrust: 500 daN
  • Maximum motor rating: 2.2 kW

Mechanical reliability of the Super KL 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 Super KL 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 below 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 230/400V 50Hz with manual or automatic control. The control signals may be 4-20mA or 0-10V.
  • Other options available: electropneumatic converters, variable frequency motors.


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

Dosing Heads:

The Super KL 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.
