Instructions and Recommendations for the Installation of

HT Series PumpsThe high-temperature pumps of the HT series havebeen designed for use in applications where the watermust be pre-heated, such as in carwash, food andpharmaceutical industries.

Maximum temperature of the water through the pumpis 185oF (85oC).

In order to obtain maximum performance in terms ofduration of seals and valves, it is necessary to respecta few simple rules, as follows:1) In order to avoid damage caused by cavitation,

the pump must be pressure fed.

The higher the inlet pressure, the longer the life ofthe wet end of the pump.

When working at 185oF (85oC), the minimumfeed pressure - measured directly in the inlet portof the pump when it is working - is 45 psi (3 bar).

The minimum feed pressure accoridng to thedifferent temperatures are:

Naturally, if the application allows for feeding thepump with 45 psi (3 bar) even at low temperatures(for example: 115oF/45oC the life of the wet end ofthe pump will be even longer.

2) The plumbing which feeds the pump must beof a diameter at least equal to the inlet port.Also, follow the suggestions below:

a) Make the plumbing as short and straight aspossible, preferably in an upward direction tofacilitate the expulsion of eventual air bubblesnaturally if compatible with the requirementsof the system.

b) It is always useful to put a filter at theinlet with capacity of 4 to 5 times the flow of

the pump, for example for a 4 gpm (15 l/min)pump, put a filter from 16 to 20 gpm (60-75 l/mi). The mesh size suitable for thisapplication is 0.016” (.4 mm).

c) It is extremely important to put a pressureswitch on the suction port of the pump, and inany case downstream from the filter, so thatit can stop the pump should the feed pressuredrop by 20% due to the filter clogging orfailure of the feed pump, etc.

3) Change of oil

We recommend the first oil change after thefirst 50 hours, with the pump stopped andthe oil still warm.

This change is not recommended because the oilhas lost its properties, but rather to eliminate theimpurities that have gotten into the oil during therunning-in phase. If these impurities are notremoved, but are allowed to remain in the oil, theymay cause premature wear to the moving partsand the oil seals. After this initial change, theoil can then be changed every three monthsor 300 hours of operation thereafter.

Please note: If the pump works in conditions withhigh humidity and with sharp temperaturechanges, it is possible that condensation willappear inside the crankcase, which mixing withthe oil can change its properties. This is easyto see because the oil changes to a white, milkycolor.

If the pump does not have excessive waterleaking from the packings, and the oil becomesmilky, the oil has to be changed more frequently.The percentage of water in the oil must notexceed 20%.
