Delivers precise, repeatable single shots of lubricant

With its precision positive displacement pump and individually adjustable air and fluid volumes, the Serv-O-Spray spray lubrication system is the perfect Minimum Quantity Lubrication solution for any operation where controlled, intermittent fluid application is needed.

  • Single-shot precision output
  • Reliable Unist pump
  • Separate air/fluid control
  • Ideal MQL solution - for short-cycle machining

Serv-O-Spray
1 signal = 1 shot of lubricant

 


  • Deliver a fixed amount of fluid with each and every shot
  • Adjustable pumps deliver 0.003 - 0.100 mL per stroke.
  • Pumps are air actuated
  • Easy adjustability and control over spray consistency.
  • Neat, clean fluid delivery - Eliminate the mess of flood coolants
  • Improves cut quality
  • Made for environmentally friendly Coolube®
  • Dry chips - higher recycling value
  • Single-shot precision output
  • Reliable Unist pump
  • Separate air/fluid control
  • Ideal MQL solution - for short-cycle machining
Outputs:
  • Intermittent output-Delivers repeatable shots of fluid
  • Multiple outputs - up to 16 pumps for 16 individual output options
Pumps(4 types available):
  • Standard 1 Drop (0.03 mL per stroke)
  • Standard 3 Drop (0.10 mL per stroke)
  • Multi-Viscosity(MV) 1 Drop (0.045 mL per stroke)
  • Multi-Viscosity(MV) 2 Drop (0.10 mL per stroke)
Actuation: Control air input with manual valve, air pilot valve, or 3-way solenoid valve (110VAC or 24VDC)
Reservoirs:
  • 16 oz. (473 ml), polyethylene
  • 32 oz. (946 ml), polyethylene

  • 64 oz. (1893 ml), polyethylene with low level

 

How it works:

  1. The Serv-O-Spray pump is ready to dispense a shot of fluid.

    Note: The system is full of fluid (green) all the way to the nozzle tip

  2. When an air signal (blue) is applied, the pump piston strokes, immediately pushing a fixed quantity of fluid out the nozzle tip. Simultaneously, an adjustable amount of air surrounds the fluid to break it up and propel it to the point of application.servservv

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


Intermittent output

Actuating your Serv-O-Spray spray lubrication system is easy. Every time a compressed air signal is supplied from an actuation valve, the pump will deliver one quick shot of fluid out the nozzle tip along with a controlled amount of air. Air continues to flow from the nozzle tip until the air actuation valve is closed. Each time air is supplied in the spray lubrication system, the pump immediately fires another shot. The pumps can be cycled as often as needed, up to 150 times per minute.

 


Separate fluid & air

Our Co-Axial nozzles keep the air and fluid separate right up to the spray tip. This unique configuration can deliver fluid over long distances without the need for excessive amounts of air. Each time the pump strokes, a metered amount of fluid sprays out the nozzle tip, and is immediately atomized by the outer jacket of air. This feature on our spray lubrication systems delivers a balanced spray pattern at the point of application.

 


Dial in the "sweet spot"

The Serv-O-Spray was designed for precise control over the fluid application with separate fluid and air volume adjustments. This means that finding the sweet spot for your application is a breeze and once it’s set, the Serv-O-Spray spray lubrication system will deliver the same amount of fluid again and again.
