Positive displacement pumps where the tubing is the only wetted part; rollers compress the tube to move fluid. Fast tube changeovers, simple cleaning and excellent chemical isolation make them ideal for labs, OEMs and production skids. PCT keeps UK stock across models and tubing, with Longer’s 3 year warranty on the range.
Single use/aseptic transfer, shear sensitive or abrasive fluids, quick recipe changeovers, or when you want the hardware to stay dry (no fluid in the pump head).
Turnkey or modular dispense platforms based on peristaltic technology, with programmable volumes, copy counts and suck back for clean cut off—ideal for filling lines and bench dispensing.
Hygienic or cleanroom dispensing, repeatable aliquots, and formats where electronic volume control and easy sanitisation matter. (Example: Longer WT600 1F dispensing—programmable volume/cycles/pause/suck back with analogue/RS 485 control)
Head only modules (no drive) for machine builders—compact footprints, defined tube sizes and materials for consistent dosing/transfer.
Panel mount integration where you own the motor and electronics, or where you need multi channel heads on a shared drive.
Drive only solutions (fixed or variable speed, stepper/BLDC), ready to pair with heads and your controls (analogue/RS 485).
When you need to standardise the motor/control platform across multiple heads and channels inside an OEM system.
Ceramic, valveless piston pumps that deliver pulseless, drift free micro to mL level dosing with only one moving part in the fluid path. Interchangeable Q Series heads (Q1/Q2/Q3) and QV/QBLDC drives cover a wide chemical range and add wash gland options.
Ultra precise dosing, long term repeatability, aggressive media compatibility, and applications where eliminating check valves avoids clogging or drift.
Compact, positive displacement gear pumps for steady micro to low flow transfer with smooth delivery, suited to OEM skids and instrument modules.
Miniaturised piston mechanisms for very small dosing in compact footprints—ideal where space is tight but precision and repeatability are critical.
Programmable, valved displacement for precise, finite volumes; great for lab automation and instrument dosing where stepwise motion and timing are key.
The consumable and only wetted part on peristaltic systems—available in multiple materials/bores for biocompatibility, chemical resistance and life. PCT holds UK stock and provides access to the Longer catalogue for fast selection.

All of our pump types can be supplied from our standard catalogue or can be customised to suit the particular needs of a given customer.
