Description

Piston pump system for spraying the smallest quantities of liquid.

Main application range:

External MQL in all metal-cutting operations. Pinpoint or small area lubrication in chipless forming operations. Application of mould release and anti-corrosion agents or other spray-on substances.

Operating principle:
The liquid flows from the reservoir into a piston pump. This pushes an exact quantity of the lubricant into the internal feed tube. Separately supplied compressed air splits the medium at the nozzle tip and sprays it.

Adjustability

  • Swept volume of the pump (manual)

  • Clock frequency of the pump (manual)

  • Quantity of spray air (manual)

  • Spray air pressure (manual)

  • Switch on/off using actuation control drive (electric, pneumatic or manual)

Pump modul L60

Pneumatically driven, finely meterable piston pump with FPM seals, manually adjustable with PMC precise metering control, enabling easy adjustment of the volume using a dial. If required, pumps with double flow volume (2DF) with up to 0.06 ml per stroke are available.

– All pumps are standard synchronous drive. Separate drive, if required (all pumps individually or certain groups). The use of the logic panel enables all pumps to be operated using only one frequency generator./font>

– Ventilation unit integrated underneath the pump module.

– Frequency generator for pump pulses, manually adjustable 0 – 90 stroke min-1.

– A dedicated air valve for each nozzle, to enable the quantity of spray air to be adjusted.

– Pressure reducing valve to set spray air pressure. It also equalizes pressure variations in the supply tube and the system and ensures that the spray profile is even.

– Manometer (0 – 10 bar) in front of door to display spray air pressure. – Coupler plug NG8 for compressed air supply to left side of housing.

– Air filter with integrated water separator and drainage opening on housing underside.

– High-grade push in/screw fittings/ pneumatic tubes.

– Stable, compact metal housing (200x200x155, 250x250x210, 300x250x210, or 400x400x210) with robust metal closer and door seal for dust protection and noise reduction, earthing pin.
