Installation
3.3 Locate and assemble the pump
Note: Surfaces of the pump are very hot during operation. If necessary, fit guard rails around the pump after you
have installed it, to prevent accidental contact with hot surfaces of the pump.
The base of the 30B5M pump has lifting-bolts (see Figure 1 ). Locate the base of the pump within practical working
distance from your electrical supply and your cooling-water supply. We recommend that you leave a gap of at least
1.6 m from the control-box end of the pump to allow you to easily replace the heaters.
After you have located the base of the pump, if your pump was supplied unassembled in two packages, assemble the
other components as described below.
1. Refer to Figure 1 . Lift the jet-stage cone (32) over the pump, then lower the vapour tube (6) and jet
assembly (3) through the inlet-flange (1).
2. Connect the vapour tube (6) to the top of the T-tube.
3. Lower the jet-stage cone (32) onto the pump, then connect the bottom flange of the jet-stage cone (32) to the
T-tube.
4. Fit the braces which support the jet-stage cone (32).
5. Fit the guard-ring (2) and the 'O' ring to the pump inlet-flange (1).
6. Inspect all 'O' ring joints and ensure that they are tight; tighten any loose joints.
WARNING
Locate the pump on a flat, secure foundation. If you do not, it may become unstable and fall over.
WARNING
Use suitable lifting equipment to move the base of the 30B5M pump. The mass of the base of the
pump is 620 kg.
WARNING
If you mount the pump off of the floor, you must fit a suitable mesh shield (with hole size less than
10 mm) under the pump, to prevent accidental contact with unprotected electrical conductors in
the pump.
