Sample Draw Pump Unit

Connects to a gas detector and draws samples of air into the gas detector from hard to access locations such as shafts, tall ceilings, wells, pits, small rooms, etc.

Uses a pump to pull sample air through a length of tube into the gas detector, across the sensor and exhaust it from the outlet port

  • Automotive Manufacturing
  • Water Treatment Facilities
  • Wastewater Treatment Plants
  • and many more...

Key Features

  • Draw samples of air from hard to access areas
  • 24 VDC or VAC powered
  • Adjustable flow meter
  • Compatible with many types of gas detectors
  • Standard water / dust tight, corrosion resistant enclosure (drip proof)

Description

The PRU is a self-contained Sample Draw Pump Unit that can be utilized with most gas detectors. It contains a pump that is designed to draw samples of air from hard to access locations such as shafts, tall ceilings, wells, pits, small rooms and other locations where it is difficult to install gas detectors. The sample draw pump pulls air from the sampling area through tubing connected to the inlet port, over the sensor and exhausts it from the outlet port. If the gas readings are higher than a specified set point, the gas detector will go into alarm.

The unit can be purchased with 24 VDC or 24 VAC operating power and includes a sample pump, adjustable flow meter, in-line particulate filter with a water tight, polycarbonate enclosure.

The tubing and flow adapter that fits CETCI gas detectors are sold separately.

Caution: The Sample Draw Pump Unit should not be used inside classified hazardous areas or to sample draw combustible gases or oxygen concentrations above 30% vol because the pump is not intrinsically safe.
