1. Introduction
JPV is composed by a plastic water tank in which an impeller driven by an electric motor forces the water into four water jets
developing suction. The water is continuously recirculated and its consumption is nil.
JPV can be connected to laboratory equipment as rotating evaporators, Buchner, Gooch or membrane filters, gel dryers,
etc. The pump produces at the aspiration tubes a residual pressure settable up to 35 mm Hg.
For the movement of equipment use the two handles located in front and rear of the tank. To remove the motor from tank
use the two lateral handles located on the plastic cover. In the upper part of the instrument a tube holder connects to the
internal Venturi ejectors which produce a maximum air flow of 22 l/minute and a vacuum residual of 35 mm Hg.
The air flow can be regulated by the proper knob. The pump is equipped by a handy door for the introduction of water and a
level indicator for maximum and minimum. A stopcock located in the rear part of the tank allows the suggested periodical
drainage. On the pipe connecting piece, inside the instrument, there is a safety valve that blocks possible water back-flows
in the suction pipe when a pressure differences arise during working cycle (black-out).
2. Assembly and installation
Upon receipt and after having removed the packaging, please check the integrity of the instrument. The box includes:
• JPV recirculating water pump
Place the instrument at about 30 cm from the walls.
The equipment is to be connected to the right electric supply by the electric cable connected to the rear of the upper part by
a panel socket with fuse. Ensure that the electric mains is earthed and that the mains socket is easy to reach.
Fill the tank with tap water through the front door up to the maximum level shown by the external indicator.
Turn on the instrument by the lighted main switch.
Air flow and vacuum level are regulated by the proper knob.
Air flow: from 15 to 35 l/minute
Vacuum:
from room pressure (1 bar) to 0.04 bar
3. Maintenance
In compliance with the product guarantee law, repairs to our units must be carried out in our factory, unless previously
agreed otherwise with local distributors. The instrument must be transported in its original packaging and any indications
present on the original packaging must be followed (e.g. palletized).
It is the responsibility of the user, to properly decontaminate the unit in case of hazardous substances remaining on the
surface or interior of the device. If in doubt about the compatibility of a cleaning or decontamination product, contact the
manufacturer or distributor.
•
Replace, periodically the tap water in the tank.
•
During operation, if necessary, replace the level of water in the tank up to the maximum level and no more to avoid
spillages. A level of water lower than the minimum can compromise pump efficiency.
During long idle periods it is suggested to empty completely the tank and to wash with tap water.
3.1 Cleaning
Disconnect the unit from the power supply and use a cloth dampened with an non-inflammable non-aggressive detergent.
