PDSP Inspection & Maintenance Schedule
These pumps were designed to infuse all the benefits of a Lobe Pump, Piston Pump, Peristaltic and Centrifugal Pump read our article, ‘5 Benefits of Using a Pomac Sanitary Self Priming Double Screw Pump’ for more information.
Routine inspection and maintenance can avoid unnecessary and expensive downtime as well as operating costs. It is recommended to regularly check:
- If the pump functions properly – excessive noise levels may indicate wear problems to bearings and gears, dragging of screws on the pump casing or cavitation.
- Pressure and Flow of the flushing system, if present
- The temperature of the heating/cooling system, if present
- Oil level in the gearbox – at standstill the oil level must be in the centre of the visual level indicator
Oil Changes
- 300 operating hours after the initial commissioning
- Every 3000 operating hours or at least every 3 months
- If not being used regularly, every 2000 operating hours, or at least every 3 months

- Pressure and Flow of the flushing system, if present
- The temperature of the heating/cooling system, if present
- Oil level in the gearbox – If the oil level has reduced, check the pump for oil leakages
- Monitor regularly the pump suction and discharge pressure conditions to ensure they are in line with typical system levels
Oil Changes
- 300 operating hours after the initial commissioning
- Every 3000 operating hours or at least every 3 months
- If not being used regularly, every 2000 operating hours, or at least every 3 months

Routine inspection and maintenance can avoid unnecessary and expensive downtime as well as operating costs. It is recommended to check the following on a daily basis:
- That the valve in the suction pipe is completely open
- That the inlet pressure is not too low in order to avoid the occurrence of cavitation
- The delivery pressure is in line with system requirements
- That the shaft seals are not leaking.
- Pressure and Flow of the flushing system, if present
- The temperature of the heating/cooling system, if present
For IG & IGH Variants periodically check the bearing oil levels. The oil must be changed annually or after every 5000 operating hours.
