This combines the advantages of PCP technology with enhanced control and monitoring within the pump – users only need to input the proportional flow ratio and the pump monitors and adjusts automatically.

Operation is simple; the SDP has an intelligent inverter drive which is programmed either locally via an HMI or centrally via a fieldbus interface. The SDP can also be controlled via analogue/digital I/Os either locally or remotely by a PLC.  

PCPs provide a constant flow rate. In the SDP, this is monitored and controlled by the pump drive which adapts to variations in operating conditions to ensure accurate repeatable dosing.

With a high potential turndown ratio of over 3000:1, flow rates from 200ml/h to 1000 l/h and discharge pressure to 48bar, PCPs offer a solution to many dosing problems. Vertical or horizontal orientation is even possible.

The SDP offers flexible, reliable, accurate dosing with low running costs and minimal chemical consumption.
