Solinst 410 Peristaltic Pump

The peristaltic pump is a reversible pump that can be used for vacuum pumping or for delivering liquids or gases. Silicone tubing runs through the U-shaped pump mechanism where it is clenched shut at 2 points by plastic rollers holding a volume of air between them. The rollers push the air in the direction dictated by the controller creating a negative pressure behind them and a positive pressure in front. By the time the 2^nd roller has lost contact with the tubing, the 1^st roller has already clenched the tubing off at the start of the next cycle creating a greater negative pressure on one side and greater positive pressure on the other.

As a vacuum pump, the lift is dictated by the surrounding air pressure. At sea level it can lift approximately 10 m, the lift decreases proportionally to height above sea level.

Solinst 425 Discrete Interval Sampler

Applications

Sampling from below LNAPL layers and Sampling of LNAPL and DNAPL

Interval sampling in lakes, rivers and wells

Sampling at points of inflow to a well

The Discrete Interval Sampler is a stainless steel chamber attached to a reel via a length of LDPE tubing. The reel has a pressure attachment for pressurising and venting the chamber. Pressure is applied using a high-pressure hand pump.

The chamber is pressurised initially which forces a check-ball valve at the bottom downwards, preventing water from entering. When the sampler is at the desired depth, the attachment on the reel can be switched to the vent the internal pressure allowing the chamber to be filled by the hydrostatic pressure around it. At the top of the chamber there is a polypropylene check-ball that floats and closes the valve when water fills the chamber preventing sample from coming in contact with the tubing. This provides a high quality VOC sample as organic compounds will not be lost via adsorption onto the LDPE tubing.

Global Water Whale Super Purger

Global Water's groundwater purging pumps provide an easy‐to‐use, high‐quality, economical solution for purging, and groundwater testing to a depth of 18m, with a maximum flow rate of 11.4 L/min. The submersible groundwater testing purging pump's 40mm (1‐5/8”) diameter minimizes well hang ups and is ideal for use in 2” or larger monitoring wells. Each purging pump is self priming when fully submersed and can be connected to a DC power source to begin pumping. Sand, rocks or debris that pass through the groundwater testing purging pump’s inlet strainer will not result in clogging. The ground water purging pumps can be run continuously for 48 hours and the groundwater testing purging pump’s life expectancy is approximately 400⁺ hours.

Observant M1 Engine Controller

The Observant M1 Engine Controller is a microprocessor based engine protection and control system for diesel and petrol engines. It offers a fully-functional engine control package, which is able to work either stand-alone, or as an integrated part of a Remote Management System. The Observant M1 enables fully automated control of pumps and generators, using input from other remote sites as a trigger to start and stop the engine.

Designed to operate in the harsh Australian climate, the Observant M1 is constructed of stainless-steel, with robust UV and weather protection. Sealed conduit entry prevents cable exposure and environmental degradation of the internal battery, fuses and wiring. Using an industry standard RS485/Modus interface, the Observant M1 fully integrates with a host of additional industry requirements and is also capable of integrating with third party SCADA systems. The Observant M1 is also covered by a three year warranty.
