Choosing a pump

To optimize

• For the best pump capacity, first work out the output you are going to require. This will include

the sprayguns themselves, and any circulation you plan to have within this system. Once you

have this figure, multiply by 1.2, and then choose the pump of which output at 30 cycles per

minute is the nearest.

• The compression ratio you will need is defined by the pressure losses due to the length and

diameter of the hosing of your system. To calculate these pressure losses, see page 99.

Example

let say you want to feed 3 conventional guns with an output of 500 cc/mn each, plus a circulation

of 0,5 l/mn.

The total output will thus be 2 l/mn. The optimal pump capacity would be: (2 000 x 1,2) ÷ 30 = 80 cc/

cycle.

The best-suited pumps will be :

the PMP 150 (output of 100 cc/cycle and

pressure ratio of 1:1) for low viscosity materials

and a small circulating (pressure loss < 3 bar).

the 02.75 (output of 85 cc/cycle and pressure

ratio of 2:1) for thicker materials and a normal

circulating (pressure loss < 6 bar).

the 04.120 (output of 240 cc/cycle and

pressure ratio 4:1) for large pressure loss in

circulating (up to 15 bar).

Pump Material Feeding

To guarantee the right delivery of product, we offer the following range of equipment for various

product viscosity :

0 - 300 cps

• suction rod.

300 to 8 000 cps

• top outlet pressure pots,

• pumps (gravity or suction rod),

• pump with base intake valve.

8 000 to 15 000 cps

• bottom outlet pressure pots,

• pumps with suction rods,

• compressor.

15 000 to 30 000 cps

• no more pressure pot,

• no more suction rod,

• submerged hydraulic pump,

• compressor,

• pump with single action elevator.

30 000 à 1 000 000 cps and +

• pumps with peak feeder and double action

elevator.
