Cole-Parmer UK offers a range of piston pumps suitable for controlled dispensing and metering applications. Piston pumps are highly accurate over long periods of operation and provide excellent repeatability. The piston pump can be run for long periods between maintenance making them suitable for continuous duty applications. Cole-Parmer’s piston pumps can deliver 0.04 mL/min to 1.3 LPM and deliver pressures up to 345 bar.
Cole-Parmer’s laboratory piston pumps are ideal for bench top use and include high pressure models for HPLC pumping applications as well as offering a wide range of control interfaces including analogue and RS-232 for connecting to a PC.
Our OEM and Industrial range of piston pumps use a valveless design. This creates a piston pump that offers enhanced reliability, simplifies troubleshooting, service and down time as there are no valves to clog and the moving parts in contact with the media is limited to just the piston. These piston pumps can deliver millions of cycles of high accuracy and drift free operation without the need of servicing.
Use Cole-Parmer’s on-line catalogue to find and compare pump specifications. Alternatively contact our Application Specialists for free technical support and let us bring over 50 years of pumping experience to help solve your application needs.
