Sureflow Control Valve system for the Papa Pump

The Sureflow automatic flow regulation system signifies another revolution in the operational ability of ram pump technology. We are the only company to design and deliver not only the unique composite Papa ram pump, but a self-regulating composite ram pump for 21st century, zero-energy water delivery

Variable water supplies and low flow rates can cause hydro rams to operate at less than maximum efficiency. Water Powered Technologies has developed the Sureflow Valve to work with the Papa Pump and ensure seamless and automatic operation where flows are small, variable or intermittent. This is especially useful in countries subject to dry seasons or low rainfall.

As the water level in the supply tank drops, a float arrangement causes the Sureflow valve to close. As the water level in the supply tank rises, the float arrangement will cause the Sureflow valve to open and the pump will automatically restart.

The Sureflow and Papa Pump combination is an ideal automatic water delivery system for installations where small or variable flows exist. It will enable automatic self-regulation and maintenance-free operation

Features and Benefits of the Sureflow Control Valve system

  • Enables the Papa Pump to operate with negligible water flows
  • Allows for one pump size to suit all flow rates
  • Works with small or variable water flows
  • Easy Fitment and Operation
    - the pump will operate at maximum efficiency for the conditions
    - no need to adjust pump settings
    - no need to stop pumps during drier periods
    - simple to install
  • Environmental Benefits - Zero Energy, Pollution Free
    - helps maintain water delivery in arid areas
    - can automatically restrict water abstraction during drier periods
  • Non-rusting - made from a modern engineering composite specially formulated for metal replacement applications

How the Sureflow Control Valve system works

With a Sureflow system fitted to a Papa Pump, as the level in the tank drops the float arrangement causes the rotary float valve to operate. This allows water pressure to act on the upper side of a diaphragm in the valve whilst venting pressure on the lower side of the diaphragm, thereby closing the valve and preventing water flow through the pump. Conversely, as the water level in the supply tank rises, it will cause the float and rotary valve arrangement to reverse the pressure on the diaphragm and allow the flow valve to re-open, automatically restarting the pump. At times of low-flow in watercourses, this system will also automatically restrict the abstraction of water when it is below a minimum level in accordance with environmental considerations. This allows the system to operate fully automatically to the mutual benefit of ourselves and the environment.
