Infusion & Syringe Pump Calibration
An infusion pump is trusted to deliver an exact volume over an exact time, often of a drug where the margin between therapeutic and harmful is small. A pump running ten percent fast announces nothing — it simply delivers ten percent more than was prescribed.
What we service
- Volumetric infusion pumps
- Syringe and microsyringe drivers
- Ambulatory and PCA pumps
- Feeding pumps
Flow rate is measured, not assumed
Pumps are mechanical devices. Rollers wear, drive gears develop backlash, and sensors drift — all gradually, all invisibly. Testing puts the pump on a calibrated flow analyser and measures what it actually delivers:
- Flow-rate accuracy at low, mid and high settings — low rates matter most, because that is where paediatric and syringe-driver errors do the most harm
- Delivered volume over a timed run, against the programmed volume
- Occlusion pressure — that the alarm triggers at the right pressure, neither nuisance-alarming nor failing to detect a blocked line
- Alarm function — air-in-line, empty syringe, door open, end of infusion
- Battery endurance under load, for transport and load-shedding conditions
- Anti-free-flow protection, where fitted
Load-shedding is hard on pumps
South African clinical environments put unusual demands on pump batteries. A pump that cannot hold charge through an outage is a clinical risk, not an inconvenience, and battery capacity degrades long before the pump reports a fault. We test endurance under actual load rather than trusting the charge indicator, and replace cells that no longer hold up.
Documentation
Each pump receives a certificate recording measured flow rates against programmed rates at each tested setting, occlusion-alarm pressures, battery performance and the next service date. Certificates are issued per serial number, so a fleet can be tracked device by device — which is what an inspector will ask for.

Common questions
Infusion pump FAQs
Annually is the standard interval for most clinical pumps. Calibrate sooner after a repair, after a pump has been dropped, or whenever a clinician reports that a delivered volume did not match what was programmed — that report is worth acting on rather than explaining away.
Yes, and it is usually the most efficient approach. We can work through a fleet on site, staggering units so you are never short of working pumps, and certificate each one against its serial number.
It can be. If the occlusion pressure threshold has drifted low, the pump alarms on normal back-pressure and staff learn to ignore it — which is the real danger. Testing establishes whether the threshold is set correctly or the alarms are telling you something genuine about the lines.
Yes. Battery capacity is tested under load as part of the service, and cells that no longer hold sufficient charge are quoted for replacement. Given how often pumps run through power outages here, this is worth keeping current.
