FINGER PUMPS

Sigmamotor Finger Pumps utilize a unique peristaltic pumping action where the pumped liquid remains inside the tubing and never touches the pump components. This makes them perfect for caustic and oil based liquids that can corrode or build up residue in other pumps. Finger pumps are perfect for machine tool lubricants.

The Sigmamotor T-8 Series Pump

The Sigmamotor T-8 Series Pump is designed to pump fluids or gases.

The unique design of the T-8 pump uses metal ‘fingers’ that are activated by a cam to progressively squeeze the tubing, gently pushing the liquid through the pump head.

Features

  • Self-Priming
  • No Corrosion
  • No Contamination
  • No Vapor Locking
  • No Valves to Clog
  • Flow Rates from .005 ml/min to 250 ml/min
  • Pump speed from 0 to 400 RPM

A wide range of flow outputs can be obtained by simply changing the tubing size and varying the speed of the pump.

The Sigmamotor T-8 pump accepts five standard tubing sizes; 1/4″, 3/16″, 1/8″, 1/16″ and 1/32″ I.D.

Applications

  • Feeding
  • Accurate Metering
  • Sampling
  • Transfer

Harsh chemicals are contained within the tubing and never touch the pump parts, thus extending pump longevity and increasing reliability.

Spring loaded pressure plates provide extended tubing life and automatically compensate for minor variations in pump tube wall thickness.

The Sigmamotor T-6 Series Pump

The Sigmamotor T-6 Series Pump is designed to pump fluids or gases.

The unique design of the T-6 pump uses metal ‘fingers’ that are activated by a cam to progressively squeeze the tubing, gently pushing the liquid through the pump head.

Features

  • Self-Priming
  • No Corrosion
  • No Contamination
  • No Vapor Locking
  • No Valves to Clog
  • Flow Rates from 5 ml/min to 2000 ml/min (0.5 gpm)
  • Pump speed from 0 to 400 RPM

A wide range of flow outputs can be obtained by simply changing the tubing size and varying the speed of the pump.

The Sigmamotor T-6 pump accepts six standard tubing sizes; 1/2″, 7/16″, 3/8″, 5/16″, 1/4″ and 3/16″ I.D. with 1/16″ wall.

Applications
