Disclaimer: We are a proud distributor for the DCP50 Positive Displacement Pump.
The DCP50 High Precision Positive Displacement Pump is a very accurate and precise positive displacement pump, especially over the entire pressure range at low flow rates. This pump is designed for laboratory applications where constant flow is needed at pressures of up to 50 bar (5 MPa, 725 psi) or at constant pressure of up to 50 bar.
What are the benefits? Keep reading to find out.
If you have a wide variety of fluids that you want to run through a positive displacement pump (PDP), this is the pump for you as it can be used for non-corrosive & corrosive solvents. As the product manual states:
“The wetted metal parts of the standard pump are made from 316 grade stainless steel and Nitronic 60. A version of pump with Hastelloy wetted parts can be ordered if working with corrosive solvents e.g. brine. A rinsing system is fitted as standard, which feeds a rinsing solution between the two cylinders behind the piston heads to clean the internal surface of the glass tubes during use. Although use of the rinsing system is optional, it is recommended for pumps being used with corrosive solvents.”
This is not your average pump, it is a lab grade pump focused on high accuracy and precision.
Here are the specs directly from the product manual:
Everyone enjoys a piece of equipment that is easy to use and does not require hours to prep. While it is recommended to leave the system out for 24 hours after receipt of shipment (as a precautionary measure in case condensation built up during a low temperature shipment), the pump can generally be set up and running within a couple hours after this wait period.
The equipment comes with 10 buttons / Indicators used for operation:
Solvent Change Button / Indicator
Use this button when wanting to change solvent as it speeds up flushing of the pump. The button has a red LED indicator to show that this feature is enabled.
Pulse Compensation Button / Indicator
Use this button when running the DCP50 against a backpressure of 5 bar or above. Operation is indicated by a red LED within the button.
Run Button / Indicator
Use this button to operate the pump. Operation is indicated by a red LED within the button.
This monitors the output flow from the pump and feeds a signal back to the internal control circuit.
6-port Switchover Valve
The valve is connected to the pistons, and switches the direction of flow around the tubing system when the pistons change direction to ensure continuous output flow. Solvent input and output are also routed via this valve.
Over Pressure Indicator
This red LED indicates when the output pressure has exceeded the limit set by the rotary control. Pump operation stops when this happens.
Pressure Safety Limit Control
This control sets the maximum pressure that the pump will operate at.
Liquid Crystal Display (LCD)
Shows the flow rate, back pressure, and the set pressure limit when running in Constant Flow mode, or set pressure, flow rate and set pressure limit when running in Constant Pressure mode. It will also show the menus for other features when selected as described in this User Manual.
Flow Rate / Pressure Control
This control sets the flow rate of the pump when in Constant Flow mode, and sets the required pressure when in Constant Pressure mode.
Switches power to the internal circuitry of the pump when turned on. O=Off, l=On
Some equipment out there does not have a lot of documentation on how to use, maintain, and troubleshoot the equipment. That is not the case with the DCP50. The DCP50 has a robust manual with 50+ pages. This manual covers installation, operation, maintenance, servicing, and troubleshooting. Not every product has a robust manual, then again not every product needs one but it is reassuring to know that the DCP50 certainly has the best interest of the user in mind by providing them with so much information about the instrument.

Are you still using the legacy Pharmacia P-500 Pump? If so, you should know that the DCP50 Positive Displacement Pump has been built to be the replacement for the Pharmacia P-500. How do they compare? Take a look at the chart below!
Stainless Steel or Hastelloy
(Not Available to Buy New)
Note: The chart above was provided by the manufacturer of the DCP50, Strata Technology LTD, and edited appropriately by Rotunda Scientific Technologies LLC.
In conclusion, the DCP50 Positive Displacement Pump is able to pump a wide range of oils, brines, and solvents (corrosive & non-corrosive). This is in large part because the pump can be used with either stainless steel or Hastelloy wetted parts. Accuracy and precision are at the top of the list in terms of importance when choosing the right pump, luckily the DCP50 can check both of these boxes with excellent flow rate precision and accuracy. On top of that the DCP50 has an easy to use interface with a robust product manual. Last but certainly not least, the DCP50 was created to be a direct replacement for the Pharmacia P-500 Pump and as the chart above shows, it meets or exceeds performance in all areas.
