How to reduce high motor power consumption in my Fristam Pump FZP 10?
- E
  eflynnAug 17, 2025
  High motor power consumption in your Fristam Pump Water Pump can be caused by several factors. If the flow rate is too high, try throttling the discharge line or reducing the speed with a frequency converter. If the impeller diameter is too large, trim it. Also, high viscosity or density of the pumping medium can increase power consumption. If there is massive damage to the shaft bearing or the shaft is deformed, disassemble, inspect, and have it repaired by Fristam.

What to do if the flow rate is too low in my Fristam Pump FZP 10?
- J
  John MillsAug 21, 2025
  A low flow rate in your Fristam Pump Water Pump could stem from several causes. First, check if the direction of rotation of the motor is incorrect and exchange the connections on the motor terminal box if needed. If the speed is too low, correct the connection according to the motor rating plate. Ensure that the nominal pipe sizes are not too small and use larger pipe diameters if necessary. High pipe resistances in the suction or discharge line can also cause this issue, so optimize the pipe system and reduce elbows and valves. Clean any clogged pipes or remove any foreign objects or deposits from the impeller. Finally, check and readjust the impeller clearance if it's incorrectly adjusted.

How to decrease the flow rate of my Fristam Pump FZP 10?
- J
  Jessica MillerAug 27, 2025
  If the flow rate of your Fristam Pump Water Pump is too high, it could be because the discharge-side valve is opened too wide; in this case, throttle the valve. Alternatively, the discharge line diameter might be too large, so reduce the nominal pipe size or insert an orifice plate. If the impeller diameter is too large, trim the impeller outside diameter or reduce the speed with a frequency converter.

What causes metal noise in my Fristam Pump FZP 10?
- S
  sharpjesseAug 31, 2025
  Metal noise in your Fristam Pump Water Pump can be attributed to a few issues. There might be foreign objects inside the pump, requiring disassembly, inspection, and repair. The impeller might be catching, necessitating a readjustment of the impeller clearance and tightening the impeller nut using a torque wrench. Also, the pump or shaft seal could be running dry, so immediately supply pumping medium and open the suction valve.

Why is my Fristam Pump FZP 10 Water Pump making flow noises?
- K
  Kathleen HaynesSep 3, 2025
  Flow noise in your Fristam Pump Water Pump can arise from a few reasons. The pump might be operating contrary to its design in an overload or part-load range, so adjust the working point to the design specifications. High flow losses in the suction line can also cause noise, so increase nominal sizes, shorten lines, and prevent outgassing. Cavitation can also be a culprit; check the conditions for NPSH rating.

How to stop vibrations in my Fristam Pump FZP 10?
- V
  vwilkinsonSep 7, 2025
  Vibrations in your Fristam Pump Water Pump may be caused by suction and discharge lines stressing the pump impermissibly. Support the pipes so that the pump is not stressed. You might also consider installing vibration dampers and keeping water hammers away from the pump.

Why is the shaft bearing of my Fristam Pump Water Pump overheating?
- A
  Aaron TaylorSep 12, 2025
  Excessive heating of the shaft bearing in your Fristam Pump Water Pump is likely due to bearing damage, which means the bearing needs to be replaced.

Why is my Fristam Pump Water Pump not pumping correctly?
- D
  davidwrightNov 13, 2025
  There are several reasons why your Fristam Pump Water Pump might not be pumping correctly. It could be due to a blocked or clogged suction line, which you can resolve by opening or cleaning the suction line. Alternatively, the suction filter might be contaminated and require cleaning. Ensure the discharge-side shut-off valve is open. If the pump isn't completely filled with liquid, adjust the pipe system to maintain liquid in the casing when the pump is idle. If you have a pump with a geodesic suction head, the liquid level might be falling at a standstill, so install a foot valve in the suction line. Other potential issues include a leaky suction line (seal it), a blocked or contaminated foot valve (reestablish its proper function and clean it), a suction head that's too high (lower the p...

How do I fix a leaking shaft seal on my Fristam Pump Water Pump?
- S
  Sharon MartinezNov 24, 2025
  Leakage at the shaft seal of your Fristam Pump Water Pump can occur due to several reasons. The mechanical seal or rotary shaft seal may have mechanical damage or wear, in which case you should replace the shaft seal and elastomers, possibly switching materials. If the shaft seal is running dry, the suction head is too high, or the pumping media temperature is too high, increase pump inlet pressure, decrease suction head, or use a double shaft seal. If the sealing water head is too high, adjust it using a throttle valve. If the sealing water head is too low, replace the rotary shaft seal. If the water tubes are clogged or the sealing water is not clean, clean the water tubes, adjust the water inlet and outlet, and use drinking water-quality water with a temperature of max. 70°C. If the tem...
