EVO 12 VOLT SUBMERSIBLE SAMPLING PUMP

Groundwater's sampling pump with a maximum delivery height of 50 metres.

The 12V DC, 5 stages pump for groundwater’s sampling with a maximum delivery height of 50 metres is provided as standard with a 50 metres cable, equipped with two-way terminal connectors, easy to couple, which can be used only with the 12V Pump Booster. The pump is also equipped with an interchangeable suction filter.The 12V DC, 5 stages pump is a multistage pump working with counterclockwise rotation, directly coupled to special submersible engines. The pump achieves the performance indicated in the table below only with fully charged battery. When the voltage indicator on the Pump Booster signals a value equal to or less than 11,5V, it is necessary to replace the battery with a fully charged one. In case of use with low battery, the pump could be irredeemably damaged. It is essential to always control that the positive ( ) and negative (-) polarities are respected on the 12V Pump Booster. It is recommended not to modify the cable length in any way. Do not use the pump in case of: pumping of liquids other than water, presence of silt or sand in the water, dry running, use for prolonged periods of more than 20 minutes.  EVO 12VDC PUMP bar 1 2 3 4 4,5 liters / min 11 8,3 5,5 3,5 2,2Supply voltage                        12VDCOperating voltage           24VDCIntensity                                   15 Amp

VACUUM PUMP 12 V

Air sampling pump.

The 12V Vacuum pump is a gas booster for the bleeding and sampling of air (both atmospheric air and soil gas). TECHNICAL DATAThe 12V Vacuum pump is a piston vacuum pump. It can work with the 12V Controller (mod. Hydrogea) that allows to vary the rotation speed of the rotor and therefore the flux of the vacuum pump. The aspiration system is equipped with a forced cooling system through a fan. Four suction sampling lines can be connected at the same time with the possibility of adjustment on each line. Three lines with  flow meter scales from 0 to 1 litre per minute, one line with a flow meter scale from 0 to 5 litres per minute. A sample outlet on delivery to the vacuum pump allows a possible analysis of the outgoing gases.The pump achieves the performance indicated on the table below only with a fully charged battery. Controlling that the positive ( ) and negative (-) polarities are respected is essential. It is recommended not to modify the cable length in any way. Do not use the vacuum pump in case of: pumping of liquids, presence of dust in the air (in this case the use of dust filters is suggested), use for prolonged periods of more than one continuous hour. USEBefore use, verify that the well, the line, the gas probe (soil gas) do not present any risk of liquid drafting by the vacuum pump.Place the case so that the lid is open and the flowmeters are in vertical position.Connect the vacuum pump to the power supply, always making sure the respect of the polarities /- . Choose a gas line (diameter 8 mm) for each flowmeter to connect and regulate each line flow. The suction flow varies according to the pressure drops (an increased length of the tube or the adding of an ampoule will certainly change the initial flow rate). 

  • Dimensions: 35 x 30 x 15 cm 

  • Weight: 4 kg

  • Power supply: 12V

  • Electric power consumption: 0,7 A 

  • Maximum combined flow: 8 l/min

  • Minimum flow: 0,1 l/min

  • Power autonomy: dependent on the type of battery

EVO 12 V PUMP BOOSTER

Flux regulator for the EVO pump with 50 metres delivery height.

The 12V EVO Pump Booster is a flux regulator exclusively dedicated at the use of the EVO 12V DC pump with 50 metres delivery height. It is equipped with two-poles female connectors that can be used only with the EVO 12V DC pump. The power supply requires a 12V battery (as for a car: the two pliers must be linked respecting the polarities red ( ) and black (-) on the battery). In case of incorrect use of the indicated polarities, the regulator is furnished with a fuse protection. The 12V Pump Booster regulator is supplied with a display indicating the battery charge during its use. When the voltage indicated on the display is equal to or less than 11,5V, it is mandatory to stop immediately the pumping in order to prevent the battery from being irremediably damaged. The battery must be replaced with a fully charged one. The regulation is carried out by the knob that serves as a switch. Do not connect the battery with the switch on. 

  • Power supply: 12V

  • Output voltage: 20V

  • Absorption: 30A

12V Low Flow Controller

12V Low Flow Controller for the 12V Sampling Pump and the 12v Vacuum Pump.

The Low Flow Controller 12V is a voltage/Ampère changer. It can work with the 12V Submersible Sampling Pump (mod. Hydrogea) or with the 12V Vacuum Pump. It allows to vary the rotation speed of the rotor and therefore the sampling pump flow or of the vacuum pump flow. The controller achieves the performance indicated below only with a fully charged battery. Always control that the positive ( ) and negative (-) polarities of the battery are respected. Do not use the controller in case of: liquids presence or use for prolonged periods of more than 1 continuous hour. USEIt is recommended to verify that the voltage controller is not exposed to water. Connect the Low Flow Controller 12V to the power supply entering its male and female bipolar connectors between the 12V Sampling Pump or the 12V  Vacuum Pump and the two clips, making sure that the polarities are respected. Switch on the controller via the changer/switch. Switch off the circuit always via the changer/switch. The Low Flow Controller 12V is protected by a 12A fuse. 

  • Rated operating voltage: 12V DC

  • Maximum absorption: 10 Amp
