Our Longer Pumps range of Syringe pumps are mainly for laboratory or OEM use.
The laboratory range of syringe pumps are available to infuse or withdraw liquids with syringe sizes from as little as 1 μL up to 100 ml.
Programming options allow for complex infusion or withdrawal processes and can include stepped functions, constant or ramped speed as well as a trigger dispense or periodic dispense.
Output signals from the pumps can show when a process has started or stopped as well as the direction. Further communication protocols can exist over RS232 or RS485.
A high pressure syringe pump allows for a linear force greater than 450N.
OEM syringe pumps allow for single and multi-channel applications.

Longer offer a 3-Year Warranty on their range of Syringe Pumps (please note this does not include OEM pumps).
The two types of Syringe Pumps available from Longer
Separated controller and Drive Unit Syringe Pump
Compact drive unit for hand-held use or to be mounted on the lab bracket
One controller can control up to 4 drive units. Each drive unit may have independent parameters
High precision (Linear travel accuracy ≤±0.5%)
Integrated Controller and Drive Unit Syringe Pump
The controller is integrated with the drive unit
Up to 10 channels, all move synchronously
High precision (Linear travel accuracy ≤±0.5%)
Working principle of the Syringe Pump - Video demonstration
Syringe pumps are able to both draw in (withdrawal) or push out (infusion) a liquid through a syringe. The volume of the liquid will be based on the size of the syringe and the method of the withdrawal or infusion will be based on the syringe pump used.
Fluid ejects at a very accurate rate when used in infusion mode. The pusher block on the syringe pump pushes against the plunger on the syringe.
When the syringe pump us used in withdrawal mode, the pusher block moves in the opposite director so that the syringe plunger is pulled and draws fluid into the syringe.
Configuration of the syringe pump
The type of syringe pump can be selected dependant on the process and application. A simple syringe pump can dispense a given volume over a set period of time. Programming options allow for complex infusion or withdrawal processes and can include stepped functions, constant or ramped speed as well as a trigger dispense or periodic dispense.
Many different syringe types exist dependant on your volume or material. Smaller volumes use glass syringes where as larger volumes use both plastic or stainless steel syringes. Stainless steel syringe’s offer both Viton or Perfluoro seals as well as being for use with higher process pressures.

The Advantages of using Syringe Pumps by Longer
Easy to define the total volume of fluid required and the time to deliver
Different syringe sizes are available dependant on the volume of fluid that is required to either be infused or withdrawn. The user can then easily programme into the pump the size of the syringe along with the desired delivery time.
High pressure delivery
Dependant on the maximum linear force that the syringe pump is able to provide will allow for the pump to either infuse or withdraw fluids in high pressure applications and processes.
Constant mean flow rate
The plunger can be set for a continuous movement, allowing for the flow rate of the fluid to be dispensed or withdrawn to remain constant.
Different syringe sizes can be used offering versatility for the process
Longer pumps range of syringe pumps offer syringe’s made from plastic, glass or stainless steel. Typical sizes available are from as little as 5 uL up to 50mL.
The Longer Advantage
Delivers precise and smooth flow, ideal for research applications
Linear travel accuracy better than ±0.5%
The minimum micro step is 0.03125 µm
Separate controller and drive unit, the drive units are light weight and are ideal for hand-held or stereotaxic injection applications
Wide range of flow rate: 0.024nL/min-150.56mL/min
Different syringe material options available for various processes and applications including: plastic, glass and stainless steel
Multi-channel models available, allowing up to 10 channels
Programmable syringe pumps are ideal for programming simple to complex processes with or without a PC
Remote pump control and PC control are available as an option
A syringe pump is a precision fluid delivery device that uses a motorised mechanism to control the movement of a syringe plunger. It accurately dispenses or withdraws fluids at controlled flow rates and volumes.
PCT supplies high-precision syringe pumps designed for laboratory, analytical, and industrial applications. These include single-channel and multi-channel options, with programmable flow profiles and low pulsation delivery.
Syringe pumps are commonly used in research, medical diagnostics, microfluidics, drug delivery, chromatography, and dosing systems. They are ideal for applications requiring ultra-precise flow and volume control.
Depending on the syringe size and pump model, flow rates can range from nanolitres per minute up to several millilitres per minute. We can help you choose a configuration suited to your application’s requirements.
Yes. Our syringe pumps offer exceptional precision and stability, making them ideal for microfluidic applications where small volumes and low flow rates are required.
Yes. By selecting syringes made from materials such as glass, stainless steel, or PTFE, the pumps can safely handle aggressive, sterile, or sensitive fluids. Contact us for compatibility advice.
Absolutely. Many models support RS232, RS485, Modbus, or TTL input/output for integration with PLCs, computers, or lab automation software. We also offer versions with touchscreen interfaces and programmable features.
Yes. Our syringe pumps can be programmed for infusion, withdrawal, or continuous cyclic operation—ideal for complex flow profiles or applications requiring bidirectional movement.
