What should I consider when choosing a pump?
Required flow at the actual head, pipework resistance, water type, duty and electrical installation.

The Clarke 750W Submersible Pump - Flow rate 216L/min is a submersible water pump intended for compatible water-circulation and transfer applications.
Select a pump by the required flow, lift/head, water characteristics and installation rather than model name alone. Actual flow normally falls as head and system resistance increase.
Sold individually. The source commercial box quantity is 4 pumps.
Key benefits
- Brand: Clarke
- Product type: Submersible Water Pump
- For compatible water-circulation or transfer systems
- Stated power: 750W
- Stated maximum/source flow figure: 216L/min
- Selling quantity: 1 pump
Choosing a pump for the system
Start with the flow required at the actual delivery height, not simply the headline free-flow figure. Vertical lift, hose or pipe diameter, bends, valves, filters and fittings all add resistance and can reduce delivered flow.
Confirm the pump is suitable for the water type, solids content, temperature and duty required. Do not assume every water pump is suitable for dirty water, continuous duty or nutrient solutions unless the manufacturer specifies it.
Submersible installation
Use a submersible pump only within the immersion, water-quality and electrical conditions specified by the manufacturer. Keep the inlet clear of debris where practical and prevent the pump from running dry if the model is not designed for it.
Pipework & flow
Use adequately sized hose or pipe and avoid unnecessary restrictions. Undersized pipework can waste pump capacity through friction loss. Secure connections and support pipework so the pump outlet is not carrying avoidable mechanical load.
Electrical safety
Water and electricity require appropriate protection. Use a suitable supply, RCD protection and connections appropriate to the environment, following the manufacturer's instructions. Isolate the pump before handling, cleaning or servicing.
Maintenance
Inspect the inlet, impeller area, cable and connections periodically. Remove debris according to the manufacturer's instructions and investigate reduced flow before assuming the pump itself has failed.

Clarke 750W Submersible Pump - Flow rate 216L/min FAQs
Does the headline flow stay the same at every height?
No. Delivered flow normally reduces as vertical lift and system resistance increase. Can I use any hose size?
Use a hose or pipe size suitable for the pump and required flow; restrictive pipework can significantly reduce performance. Can the pump run dry?
Do not assume so. Follow the manufacturer's instructions for the exact model. Is it suitable for dirty water or nutrient solution?
Only where the manufacturer confirms compatibility with the liquid and solids content involved. What electrical precautions are needed?
Use a suitable protected supply and installation for the wet environment and isolate power before handling or servicing. What should I check if flow drops?
Inspect the inlet, pipework, filters, fittings and impeller area for restriction or blockage. How should the pump be maintained?
Follow the manufacturer's cleaning and servicing instructions and inspect cables and connections regularly. How many pumps am I buying?
The selling unit is one pump. The source commercial box quantity is four.
