1TechnicalData

Note: *Performance is limited only by the temperature and pressure of the water supply. At a water pressure of

1.4 bar (20 lbf in-2) and a temperature of 15 ºC, the pumping speed is approximately 3.9 l min-1, and the

ultimate vacuum 17 mbar. Water consumption is approximately 625 l h-1.

The Model 10 pump operates from standard water supplies to produce rough vacuum for application in the

distillation, filtration aeration fields and general duties not requiring higher performance mechanical vacuum pumps.

Construction

2Construction

The pump is constructed from a plastic material (PPS) which has high corrosion resistance properties. The material

is non-flammable and is resistant to a wide range of solvents, mineral and organic acids and alkalis. It must NOT be

used with the following:

Bromine (wet)

Butyl Amine

Chlorosulfonic Acid

Chlorine (dry)

Chromic Acid Conc

Hydrogen peroxide 30%

Morpholine

Nitric Acid 35% to Conc

Sulphuric Acid 98%

Trichlorethylene

Riffled nozzles are provided on the pump for the water and vacuum connections and an internal non-return valve

prevents flooding of the vacuum system in the event of fluctuating water pressure.

3 Installation notes

1. Connection to the water supply should be made using 12 mm bore tubing and to the vacuum system using 7 mm

bore vacuum tubing. If it is desired to fit a water drain, thus should be of 9.5 mm bore tubing.

Note: After considerable service, the tubing may stick to the nozzles and it should be removed by cutting.

2. Should the jet nozzle assembly or the vacuum connection be removed:

Ensure ball valve is located correctly in the vacuum arm, on re-assembly, so that the pin projects towards

the centre line of the jet nozzle assembly.

The vacuum nozzle should be carefully tightened to a torque setting not exceeding 18 lbf in (maximum) and

the jet nozzle to a torque setting not exceeding 24 lbf in (maximum).

CAUTION

The ball valve is manufactured from an elastomer which is liable to swell in the presence of certain chemical

(particularly ketones and esters). Should the pump cease to operate when such chemicals are present, then the

valve is suspect and should be inspected. Access to the valve is obtained by unscrewing the vacuum nozzle.

Renew the valve ball if swollen or deteriorated.
