Overview
Aries Ram Pumps are fully automatic. Water flows through the pump and closes the waste valve this causes a pressure wave which opens the check valve and sends water out into the delivery pipe and into the chamber pressurising the air in it. The pressurised air gives the delivery pipe 'charge' an extra boost. At the same time the initial pressure wave opens the waste valve and water starts to flow through the pump again until it's rate of flow closes the waste valve and thus begins a new cycle.
How It Works
Aries Ram Pumps Main Components:
Drive Pipe
The drive pipe is a rigid pipe which performs the task of providing the required 'fall' of water into the pump and also contains the pressure wave created each time the pump cycles (normally around once per second). It's length can be tuned depending on the installation, but is normally between the limits shown on the graph in Technical Specs.
Waste Valve
The waste valve closes when water flows through the pump and creates the pressure wave which is the basis of the ram pump operation. It opens again with the back pressure wave allowing the cycle to begin again.
Check Valve
The check valve allows water flowing through the pump to be re-directed to the delivery pipe, It closes when the pressure chamber forces water out of the delivery pipe, stopping water going out of the delivery pipe from flowing back into the pump body.
Air Chamber
The air chamber is pressurised by the action of the pump and is critical to pump performance as it provides a boost to the pumped water flowing out through the delivery pipe. It also smooths out the pulses in the delivery pipe.
Delivery Pipe
The delivery pipe runs from the pump outlet to wherever the water is needed. Normally this is many feet from the pump and a t a considerably greater height. Anti-kink hose should be used to ensure constant delivery.
