CombiPrime V 2.5.2 Shaft sealing On both sides of the self-priming part there is a mechanical seal or a number of lip seals. Both are mounted on shaft sleeves, which have been sealed in such a way that the pumped liquid cannot touch the pump shaft. The mechanical seals meet EN 12756 (DIN 24960), with the exception of the mounting length.
Re-use The pump may only be used for other applications after prior consultation with Johnson Pump or your supplier. Since the lastly pumped medium is not always known, the following instructions should be observed: • Flush the pump properly. • Make sure the flushing liquid is discharged safely (environment!) Take adequate precautions and use the appropriate personal protection means (rubber gloves, spectacles)! Scrapping...
CombiPrime V 3 Installation Safety • Read this manual carefully prior to installation and commissioning. Non-observance of these instructions can result in serious damage to the pump and this will not be covered under the terms of our guarantee. Follow the instructions given step by step. •...
Mounting 3.4.1 Installation of a pump unit Pump and motor shafts of complete pump units are adjusted perfectly in line in the works. 1 In case of permanent arrangement place the base plate level on the foundation with the aid of shims. 2 Carefully tighten the nuts on the foundation bolts.
CombiPrime V 3.4.3 Alignment of the coupling 1 Use bolts (0890) to position the electric motor in such a way that the coupling halves are aligned correctly. 2 Place a ruler against the coupling. The ruler should touch both coupling halves over the entire length, see figure 2A.
Piping • The piping to the suction and delivery connections must fit exactly and must not be subject to stress during operation. • The passage of the suction pipe must be amply dimensioned. This pipe should be as short as possible and run towards the pump in such a way that no air pockets can arise.
CombiPrime V Vacuum pump with service liquid tank 3.7.1 Mounting of accessories • Connect a pipe to the overflow of the service liquid tank to discharge excess service liquid and extracted air. • The pump is supplied with the exhaust pipe connected to the pump cover. 3.7.2 Connection diagram with service liquid tank Figure 4:...
3.7.4 Installation examples with service liquid tank For a few situations is shown how pumps with a service liquid tank can be installed. Excess service liquid must always be discharged to the suction tank separately. Figure 5: Medium: thin, clean and slightly polluted liquids. Installation CV/EN (1009) 5.3...
Page 24
CombiPrime V Figure 6: Medium: thin liquids, polluted with highly abrasive constituents. The back blades on the centrifugal impeller prevent heavy abrasive matter from getting into the suction space behind the impeller. To prevent floating abrasive matter from penetrating the pump, mount a filter in the suction pipe.

Page 29
Figure 11: Medium: thin liquids polluted with highly abrasive matter. The back blades on the centrifugal impeller prevent heavy abrasive matter from getting into the suction space behind the impeller. To prevent floating abrasive matter from penetrating the pump, mount a filter in the suction pipe. The straining capacity of the filter should correspond with the nature of the pollutant.

CombiPrime V Figure 12: Medium: thin, clean and slightly polluted liquids. In case part of the suction pipe lies higher than the pump, venting should also be provided in this part. If the suction pipe is short, or the lift in the suction pipe small, venting at the highest point is not necessary.
Figure 13: Medium: thin, clean and slightly polluted liquids. In case of long suction pipes (10 m or more) and a high suction head (4 -7 m), also the suction pipe must be vented. Connection of the electric motor The electric motor must be connected to the mains by an approved electrician, according to the locally prevailing regulations of the electricity company.
CombiPrime V 4 Commissioning Inspection of the pump Check whether the pump shaft turns freely. Do this by turning the shaft end at the coupling a few times by hand. Inspection of the vacuum pump part 1 Check whether all piping between the pump wheel casing and the service liquid tank (version TL) or the float-controlled de-aerator (version VL) have been connected.
Adjusting the air-inlet valve The air-inlet valve (1650) serves to admit small quantities of air into the self- priming system. The vacuum pump has been designed to pump a large quantity of air. After the suction phase, the vacuum pump functions as liquid pump. However, in principle it is not designed to only pump liquid.
CombiPrime V 5 Maintenance Daily maintenance Regularly check the outlet pressure. No water should get into the terminal box of the electric motor when the pump room is sprayed clean! Never spray water on hot pump parts! The sudden cooling down may cause them to burst and hot water may flow out! Service liquid After the pump has been put into operation once, the working-liquid tank and the float- controlled de-aerator don't have to be filled up again: there is constantly a sufficient...
Environmental influences • Regularly clean the filter in the suction pipe or the suction strainer at the bottom of the suction pipe, as the inlet pressure may become too low if the filter or the suction strainer is fouled. • If there is a risk that the pumped liquid expands during solidification or freezing, the pump has to be drained and, if necessary, flushed after it has been put out of service.
CombiPrime V 6 Problem solving Faults in a pump installation can have various causes. The fault may not be in the pump, it may also be caused by the pipe system or the operating conditions. Firstly, always check that installation has been executed in accordance with the instructions in this manual and that the operating conditions still correspond with the specifications for which the pump was purchased.
