Accessories for 12V pumps

Grundfos MP1 Pumps

The MP1 pump is specially designed for purging and sampling monitoring wells with a diameter of at least 50 mm and a depth up to 90 meters. The pump motor is controlled by a special adjustable frequency converter. Since the frequency is continuously adjustable, the capacity of the Grundfos MP 1 pump can be controlled from 0 to 2 m³/hour. This creates a constant flow of anaerobic water.

Each new measurement must be purged before samples can be taken. The large capacity of the MP1 pump ensures that the measuring point is quickly purged. By setting it at a lower pumping capacity, the MP 1 can also be used for sampling. Built-in safeguards protect the MP1 pump and frequency converter against overloads. The actual frequency can be read out on a display.

Benefits of the MP1 submersible pump are:

• High pumping capacity for purging, slow pumping for sampling
• Easy to install; mobile
• Resistant to corrosive liquids
• The pumped material only comes into contact with stainless steel and Teflon
• Anaerobic sampling
• Simple cleaning procedures

Inertial pumps (ball valves)

Stainless steel ball valves to be used as inertial pumps with PE tubing. 

The Inertial Pump is a groundwater pump, simply consisting of a riser tube with a one-way valve at the foot. The valve allows water to enter the tubing as it is pushed downward, and retains the water when the tubing is pulled upward again. The inertia of the water itself provides the force to carry it up to the surface.

Eijkelkamp peristaltic pump 12V

The peristaltic pump, specially designed for use in the field, is battery powered and microprocessor controlled. The microprocessor enables an adjustable constant number of revolutions (which can be stored in memory), protection against overload and various modes of external control. Controlling the peristaltic pump can be executed via the key-pad on the front panel. A built-in maintenance free 12 Volt battery enables you to use the pump 2 to 5 hours continuously (depending on load). The pump, with CE certification, is splashproof (IP 64) and can be used in the field without problems. The apparatus can be used in all positions. The pump is designed for long-term professional use in unfavourable circumstances.

Benefits of the peristaltic pump 12 V:

• Integrated 4.5 hrs battery, no spaghetti of cables
• Samples all wells with water tables < 9.5m
• Ideal to purge AND sample low volume wells
• Pumps 100 – 2300 ml/min
• Ideal for micro-purging and low flow sampling
• Low loss of volatiles if used with 6x8 PE tubing and suction <6 meters water
• No cross contamination: Exchangeable cheap and contaminant free tubing
• Renewable tubing cares for highest reproducibility of sampling results on volatiles compared to other pumps
• Pumps air as well as water
