What Types of Pumps Can Be Integrated With the DICE™?
All the DICE™ chemical dosing modules can be integrated to any type of dosing pump.
Progressive Cavity Pumps
Diaphragm Spring Loaded Valve
The only difference in the DICE™ integration is the diaphragm spring loaded set point.
The DICE™ is equipped with a diaphragm spring loaded valve that serves three purposes.
1. A Back Pressure Maintaining Valve
For diaphragm dosing pumps, the valve maintains a constant discharge pressure, allowing for precision and reliability.
2. A Non Return Valve
The valve design allows for a great non return capability with an extremely efficient sealing.
3. Anti-Siphon Valve
The spring loaded diaphragm valve also acts as a anti-siphon valve.
The Valve Set Point
Diaphragm Dosing Pumps
For a diaphragm dosing pump, the spring loaded valve should act as a back pressure valve. Therefore, the set point should be slightly higher than the process pressure.
Progressive Cavity Pumps, Gear Pumps & Vane Pumps
For these types of pumps, the valve set point should be lower than the process pressure. It allows the valve to have a minimal pressure loss during pump operating while acting as a check valve if required.
Peristaltic pumps being sensitive to outlet pressure, it’s important not to uselessly increase the outlet pressure seen by the pump. Therefore, the set point should be lower than the process pressure.
