Two years or 5000 hours, any type of tubing. Please see our warranty page for more details.

Warranties vary and may require the use of that manufacturer's brand of tubing.

Works at +/– 5% over its speed range and the life of the tube.

Most must be hand-calibrated and verified.

Patented design keeps older, swollen tubes from pinching and rubbing, for longer tube life.

Swollen tubes can pinch and rub inside competitor pumps, causing premature failure.

Our double-sealed, synthetic-lubed bearings are impervious to contamination. All parts are stainless steel or coated to resist all but the strongest alkali solutions.

Competitor pump rollers can become contaminated and seize, causing premature failure. Also painted/plated steel, and plastic, become susceptible to UV and chemical degradation.

Four bolts or less remove any component. All parts available individually "off the shelf."

Often built to be disposable, or integrated with a drivemotor, which limits serviceability.

Rebuild your Accu-Staltic at a fraction of a new pump's cost, often within an hour.

Competitor pumps offer limited ability to rebuild the product.

Wide range of options include a sensorless AC Vector, DC, hydraulic, or mechanical link.

Primarily low power DC drives.

One drivemotor can turn up to 24 pump channels with 1/2" tubing with our pumps.

Most pumps are single-channel with limited multiple channel capabilities and tube sizes.

Positive occlusion (seal) is guaranteed with any commercially-available tubing.

Pumps may need to be adjusted to prevent backflow, and may backflow under pressure.

Hoses can be inspected without a total pump disassembly, making for easy routine maintenance.

Many models must be disassembled to inspect hose; hard to know when it might fail.

Pump sizes can handle a range of tube sizes, with flows from a few mL per minute to 16 LPM, by reconfiguring manifolds.

Most models are built for a single tube size, so if you need to change your flow rate you must also change your pump.

Handles pressures to 70 PSI and higher, with the proper tubes, with minimal effect on flow rate.

Can't perform under pressure without flow rates degrading or motor stalling.
