Metering pumps

Type LDD. Variable eccentric pump drive.

Performance:
Pressure up to 7 bar
Flow rate up to 4,5 m3/h per pump head
Temperature up to 400°C

 

  • Rod thrust: 6 kNshell-and-tube heat exchangers
  • Stroke length: 30 mm
  • Stroke adjustment: available with fixed stroke length or with stroke length adjustment. Setting of stroke length is carried out manually or electrically
  • Linear stroke adjustment in steps of 0.01 mm via hand wheel while pump is stopped or in operation. Proven variable eccentric drive principle, that means stroke length is adjusted where it arises: at the eccentric
  • API 675 specification is met
  • Differing stroke rates make it possible to meet requirements for different fluids and process conditions
  • Pump head types: plunger- and diaphragm pump heads can be mounted
  • Drive: AC and DC motors, frequency inverter possible
  • Attachable instruments: contactor

Method of operation

The drive shaft turns the eccentric via the worm gear and the hollow shaft. The connecting rod converts the rotary motion of the plunger rod. The stroke length for the displacer movement is set (with the pump stopped or in operation) through radial shifting of the eccentric. For this the sliding shaft is axially shifted via the adjusting spindle. The axial movement of the sliding shaft is converted into a radial movement of the eccentric via the skew-slotted groove in the hollow shaft.
