Design Specifications

The principles of the Papa Pump technology are based on 300 year old ram pump technology. The flow of water through the system for delivery : how much water is supplied to the pump, the height of the supply head and the height of the delivery head The performance of the Papa Pump can be determined in the training manual. The Papa pump is supplied with a delivery hose assembly, an 8 L pressure vessel, a 5.08 cm BSP lever ball valve, an exhaust insert, 2 Seradisc filters, a multi-purpose tool, a set of spare O-rings and valves and a comprehensive manual. Pump body items: Latigloss ® - high-performance thermoplastics (approved potable water application verified by WRAS, NSF and ACS.) Metal items: Stainless steel Valve members/O-rings: EPDM Exhaust insert: Polypropylene Max Output (L/day): 20,000 Max operating pressure (bar): 10 Weight: 2 kg Length x width x height: 30 x 18 x 16 cm Inlet/outlet ports: 5.08 cm (2”) BSP (50 mm nb) Delivery port: 2.54 cm (1”) BSP WRAS approval: Cold water use up to 23o C

Product Schematics

Technical Support

Water Powered Technologies specify the Papa Pump is simple and easy to install. The website provides detailed technical data, and training guides for installation and maintenance.

Replacement Components

Replacement components include: O-rings, Main valves, NR valves, and pressure relief valves. The only moving parts are rubber valves and these are the only components that need replacing every few years (2-3).

Lifecycle

The Papa Pump is guaranteed for 5 years, with an option for a 10 year guarantee.

Manufacturer Specified Performance Parameters

The designer specified performance targets include: durable, lightweight, requiring no fuel or electricity, operating without manual intervention 24/7 when at least 50 L/min of water is supplied through the pump, minimum of 70% of the water is depressurized and ejected and maximum of 30% is pressurized and delivered to high elevations or long distances.

Vetted Performance Status

Testing performance has been conducted by the manufacturer to determine water supply for variable supply and delivery heads, and to pressure test up to 50 bar. No third party testing has been completed.

Safety

The are no known safety issues associated with the product.

Complementary Technical Systems

The product can be implemented into off-grid micro energy generation. Multiple Papa Pumps can be installed in parallel in settings of large flow and higher water delivery requirements. The manufacturer also offers automatic flow regulation systems (SUREFLOW), additional filtration screens (Seradisc) and rainwater recovery technology as a water source (Hydromentum).

Academic Research and References

Compliance with regulations

The product is verified by WRAS, NSF and ACS.

Evaluation methods

The manufacturer specifies water pressure up to 50 bar and 30% pressurised supply water for delivery. The manufacturer evaluates the product based on supply head, input capacity, the desired delivery head and the desired litres per day as evaluation criteria.
