Based on the search results, it seems PriceCheck has several great options for water pumps that may interest you! The Sobo 5W Aquarium Submersible Water Pump looks like a good basic choice at just R245. If you need something higher powered, the 750W Submersible Water Pump for R2112 or Max Pumps Water Pressure Pump for R2469 could be suitable. These pumps seem suited for moving larger volumes of water. I hope these suggestions are helpful as you select a pump that best meets your needs. Please let me know if you have any other questions!
