Why is the flow rate too high in my Fristam Pumps Water Pump?
- D
  Daniel JonesAug 17, 2025
  If the flow rate of your Fristam Pumps Water Pump is too high, it could be because the discharge-side valve is opened too wide or the discharge line diameter is too large. Try throttling the valve or reducing the nominal pipe size by inserting an orifice plate. Alternatively, the impeller diameter might be too large; in that case, trim the impeller outside diameter or reduce the speed with a frequency converter, or contact Fristam.

What to do if my Fristam Pumps Water Pump is making metal noise?
- B
  bdunnAug 21, 2025
  If you notice metal noise coming from your Fristam Pumps Water Pump, it could be due to foreign objects inside the pump. Disassemble, inspect, and repair the pump. Another cause might be the impeller catching. Readjust the impeller clearance and tighten the impeller nut using a torque wrench. Also, check if the pump or shaft seal is running dry and immediately supply pumping medium or open the suction valve.

Why is the motor power consumption too high in my Fristam Pumps Water Pump?
- A
  Amanda GalvanAug 25, 2025
  If the motor power consumption of your Fristam Pumps Water Pump is too high, it could be due to a flow rate that is too high. Try throttling the discharge line or reducing the speed with a frequency converter. Another reason might be that the impeller diameter is too large, so trim the impeller diameter or contact Fristam. The viscosity or density of the pumping medium could also be too high, in which case you should contact Fristam. Lastly, massive damage to the shaft bearing or a deformed shaft could be the cause; disassemble, inspect, and have it repaired by Fristam.

Why is my Fristam Pumps FP making flow noise?
- D
  Denise Manning MDSep 3, 2025
  If your Fristam Pumps Water Pump is making flow noise, it could be due to operation contrary to design in overload or part-load range. Adjust the working point to the design. High flow losses in the suction line could also be a cause; increase nominal sizes, shorten the line, and prevent outgassing. Another possibility is cavitation. Check the condition for NPSH rating and contact Fristam.

How to reduce vibrations in my Fristam Pumps Water Pump?
- A
  Angie HansonSep 6, 2025
  If your Fristam Pumps Water Pump is experiencing vibrations, it could be because the suction and discharge lines are stressing the pump impermissibly. Support the pipes so that the pump is not stressed, possibly install vibration dampers, and keep water hammers away from the pump.

How to troubleshoot a Fristam Pumps FP Water Pump that is not pumping correctly?
- K
  Kellie RuizNov 13, 2025
  If your Fristam Pumps Water Pump isn't pumping correctly, it might be due to several reasons. The suction line could be blocked or clogged, or the suction filter might be contaminated. Try opening or cleaning the suction line and cleaning the suction filter. Also, make sure the discharge-side shut-off valve is open. If the pump isn't completely filled with liquid, adjust the pipe system to keep it filled when off. For pumps with a geodesic suction head where the liquid level drops at standstill, install a foot valve in the suction line. If the suction line is leaky, seal it. Ensure the foot valve isn't blocked and clean it if necessary. Reduce the suction head if it's too high, and ensure the suction line has a steady incline to prevent air pockets. If there's excessive air or gas in the p...

What causes low flow rate in my Fristam Pumps FP?
- A
  Alexandra BakerNov 26, 2025
  If your Fristam Pumps Water Pump has a flow rate that is too low or a discharge head that is too low, it could be due to several reasons. The pump or the impeller diameter might be too small, in which case you should contact Fristam or replace the impeller. Check if the direction of rotation of the motor is incorrect and exchange the connections on the motor terminal box if needed. Also, the speed might be too low due to incorrect voltage; 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 could also be the cause; optimize the pipe system and reduce elbows and valves, or contact Fristam. Clean any clogged pipes or pipes full of dep...

How do I fix a Fristam Pumps FP Water Pump shaft seal leak?
- T
  tracy48Dec 1, 2025
  If you are experiencing leakage at the shaft seal of your Fristam Pumps Water Pump, the impeller nut might be loose. To fix this, remove the impeller, inspect the shaft shoulder, check the shaft seal, and tighten the impeller nut to the required torque, replacing parts if necessary. Alternatively, the shaft seal or rotary shaft seal might have mechanical damage or wear, in which case you should replace the shaft seal and elastomers, possibly switching materials or contacting Fristam. If the shaft seal is running dry, the suction head is too high, or the pumping media temperature is too high, increase the pump inlet pressure, decrease the suction head, use a double shaft seal, or contact Fristam. If the sealing water head is too high, adjust it using a throttle valve. If the sealing water h...
