2. Installation of the Pump
2.5 Connecting steam or steam condensate for aseptic use
Shaft seals for aseptic use are supplied with stainless steel connectors
(18” NPT x 1/4” Tube).
The connection for steam or steam condensate with a static double seal
in the pump body is supplied with stainless steel fittings (1/8” NPT x 1/4”
Tube) and 1/4” stainless steel tubing.
Steam can be used at temperatures up to 300°F (150°C) and pressures
up to 72 PSIG (5 bar).
Before starting the pump, dismantle and clean the suction pipe. Any
foreign material in the pump should be removed.
3.1 Checking the pump body for foreign material
Remove the pump body as described below. The assembly drawing is to
be used for reference (page 8).
1. Disconnect the power supply.
2. Remove the pump body (item 1a) by undoing the clamp ring
(item 9a) or body screws and carefully pull off the pump body.
3. Turn the impeller (item 4) to ensure that there is no foreign material
behind it.
4. If there is any foreign material in the pump, remove it.
5. When the pump body is clean and free of foreign material,
reassemble the pump.
Mount the pump body as described below:
6. Check that the locating pin (item 8), where fitted, in the top of the
back plate mates with the detent in the pump body and carefully, to
avoid damaging the O-ring, press the pump body (item 1a) in over
the o-ring (item 6) and fasten with the clamp ring (item 9a) or body
screws, observing the correct tightening torque.
M8: 22 ft-lb (30 Nm)
M10: 41 ft-lb (55 Nm)
M12: 80 ft-lb (59 Nm)
7. Install suction and discharge pipes. Check that the pipe unions
have been tightened properly and that pipe supports have been
fitted.
To make the pump body easier to fit, we recommend that you give the
O-ring a thin layer of food-approved, acid-free grease or soap.
3.2 Testing the pump
To check that the pump is working satisfactorily, pour water into the
pump and start it for a moment. Check the direction of rotation (fig. 2).
Listen for any unusual noises.
In pumps with water-flushed or steam-flushed shaft seals, the seal
chamber must be filled with water/steam.
Never allow the pump to run without liquid, as this will ruin the shaft seal.
