Peristaltic Pump (Advanced)

Advantages

The Peristaltic Pump - Advanced is an electronic peristaltic pump with advanced memory option. This reliable and universal electronic peristaltic pump can create a perfect vacuum; it is a versatile pump for sampling and purging in shallow wells. Peristaltic Pumps are used for low flow sampling of groundwater; this pump is perfect for the attachment of an in-line filter, for use with a flow-through cell and multi parameter probes. Available with optional auto shut off to assist compliance with the latest standards and directives when low flow sampling in monitoring wells.

Benefits:

  • Reliable and easy to use and maintain
  • Splash proof for use in the field (IP64)
  • Built in maintenance free battery that runs between 2 and 5 hours depending on conditions & charging
  • Can pump product and water even if it contains sediment
  • Optional auto shut-off for draw-down control
  • Cheap disposable tubing - no chance of cross contamination.

Bladder Pumps & Geocontrol Pro

Advantages

A small, portable, very efficient package that includes a built-in high efficiency electrical compressor and optional auto shut off makes these bladder pumps ideal low flow groundwater sampling pumps capable of pumping from depths of up to 60 metres. The small electric compressor uses an external rechargeable lead acid battery. Air does not make contact with the liquid. These stainless steel pumps use a replaceable bladder either in Teflon or PE for easy cleaning and prevention of sample cross contamination and with diameters starting at 22mm to fit in a 1-inch well. Bladder Pumps are ideal groundwater sampling pumps.

Benefits:

  • Very small, highly efficient package
  • Controller with built in high efficiency electrical compressor
  • Small, lightweight and very portable
  • Easy to use
  • Dedicated systems available for best low flow results
  • Pumps to depths of 60m or more in 1" diameter or larger wells
  • Stainless steel pump is easy to clean and maintain
  • Intrinsically safe design - pump operates on compressed air
  • Disposable bladders and tubing mean no cross contamination
  • Accessories and consumables are readily available and very cost effective
  • Available in 42mm and 22mm sizes
  • Shorter pump is ideal if wells are not straight
  • Strong hose barbs - requires no safety cable
  • Can sample both product and water from contaminated wells
  • Can be run straight from a car cigarette lighter socket (recommended).

Specifications: Bladder Pump & Geocontrol Pro

Technical specifications
Max pressure: 100psi
Power supply: Hand held 12v battery or car cigarette lighter socket
Head lift of water: 60m

Stainless Steel Geosub Pump

Advantages

The SS Geosub Pump is a low voltage, stainless steel, submersible sampling and purging pump. It has a number of attributes which make it the ideal environmental groundwater sampling and purging tool. This pump is powered by DC voltage making it very safe to use. It is suitable for continuous operation and is tolerant of sediments, except clay. The pump is capable of impressive flow rates and will serve well as a combined sampling and purging pump to depths up to 45 metres. It is packed with convenient features like the dry-run power-save, easy decontamination, and field replaceable motor leads.

Benefits:

  • Low Voltage DC power - safer than high Voltage AC pumps
  • Dry run cut off can save energy
  • Pump is suitable for continuous operation
  • The pump is rated at 2000 hours of use in CLEAN water. In common with other impeller type pumps, sediments can cause damage and reduction in pump flow rate performance is an early indicator.
  • Pumps to depths of 45m in 2" diameter or larger wells
  • Step-less control for flow rates from a trickle to 13 litres per minute
  • Pump is stainless steel so can be de-contaminated
  • Up to 80 different well settings can be stored and programmed

Specifications: Stainless Steel Geosub Pump

Technical specifications
Pumps down to: 45m
Diameter: 42mm
Product material: Stainless steel
Tubing: 10 x 12 Polyethylene 75m roll
Flow rate: Up to 13 Litres per minute
Power Supply: 110V Generator

MP1 Pump

MP1 Pump (Variable Frequency Drive)

Advantages

The MP1 Pump is an electric impeller driven pump that can be used for sampling and purging deep wells. The MP1 is the perfect groundwater sampling or aquifer test pump. The MP1 Pump, which can be controlled by a Variable Frequency Drive (VFD), can precisely and smoothly control the water flow from 0.1 litres per minute to 34 litres per minute – high flow rates for purging, low flow rates for sampling. The MP1 fits wells of 2-inch diameter and is capable of pumping to a depth of 90 metres. This pump can be damaged by (suspended) sediments or sand so is not ideal for well development in these conditions. The MP1 Pump requires 110V generator or mains supply.

Benefits:

  • Pumps to up to 90m in 2 inch diameter or larger wells
  • Step-less control for flow rates from 100ml to 34 litres per minute
  • Pump is stainless steel and the cord is teflon coated so can be decontaminated.
  • Can be used for sampling and purging deep wells.

Specifications: MP1 Pump

Technical specifications
Diameter: 42mm (without cooling shroud attached)
Well size: Fits wells of 2 inch diameter
Power supply: 110V Generator
Pumps down to: 90m
Product material: Stainless steel
Flow rate: 34 Litres per minute
Tubing required: 12x16mm Polyethylene discharge tubing
Power cord: Teflon coated
