Pump Comparison Guide

Laboratory pumps are used to move liquids or gases for tasks like filtration, distillation, and sample aspiration, or to create a vacuum for applications such as rotary evaporation, sputter coating and freeze-drying. Vacuum pumps are specifically designed to remove air from a sealed space to create negative pressure, while other types, such as peristaltic, syringe, or diaphragm pumps, are used for fluid transfer and metering.

What kind of Pump is suitable for your application?

Type

Rotary Vane Pump

Dry Scroll Pump

Diaphragm Pump

Syringe Pump

Peristaltic Pump

How it works

Rotating parts like lobes, gears, or vanes to trap and move fluids usinf positive displacement.

Two interleaved scrolls, one fixed and one orbiting trap, compress, and move gas.

Flexible diaphragm moves back and forth to create a variable volume inside the pump chamber

A motor-driven plunger moves in a syringe to push fluid.

Rollers compress a flexible tube to push fluid forward.

Application

High flow rates and high pressure, viscous fluids and slurries, applications where fluid contact with pump parts is acceptable.

Scanning electron microscopes, gas chromatography mass spectrometry, and leak detectors, cryostats, beam lines, vacuum ovens and high-energy physics.

Chemical processing, mining, wastewater treatment, pharmaceuticals, and food and beverage industry. Applications for abrasive, viscous, and sensitive liquids without contamination.

Precise, low-flow applications like microfluidics, drug delivery, and sample injection.

Continuous, high-flow applications, media circulation, and filtration.

Flow Style

Steady, low-pulsating flow. Flow rate is directly proportional to speed.

Steady, continuous flow, compression of gas in enclosed, pockets avoids pulsations.

Pulsating, non-uniform flow from back-and-forth motion of diaphragm and check valves.

Steady, continuous flow, can exhibit minor pulsations at low flow rates.

Pulsating flow, constant, proportional flow precisely controlled by adjusting speed.

Accuracy

High precision is possible, dependent on design and fluid properties.

Very high precision, but high accuracy dependent on design.

High accuracy and precision, very consistent and precise flow rates.

Very high precision and accuracy.

Moderate accuracy, improved by calibration.

Pressure

Low to very high pressure from >80mbar to 10-4mbar.

Medium to high pressure from 1000mbar down to 10-3mbar.

Low pressure from 8.6bar to 200bar.

Low pressure to medium from 0.7bar to 1.39kbar.

Low pressure up to 16bar.

Hazards

High contamination risk with motor-fluid, moisture and particulates. Possible microbial growth.

Low contamination risk, oil-free. Potential from particles generated by internal wear, corrosive gases, or ambient air.

Low contamination risk, physically separates fluid from mechanical drive components.

High contamination risk with motor-fluid and syringe parts in contact.

Low contamination risk with pumping fluid only in contact with tubing.

Service & Care

Regular oil changes, filter replacement. Inspection for leaks, noises and wear. Follow manufacturer's guidelines for oil type.

Regular cleaning, replace seals, filters and bearings. Inspections for noise, high temperatures and of external fans. Follow manufacturer's guidelines.

 Regular diaphragm and valve changes. Inspection of lubrication, fluid flow, air supply, fittings and connections. Follow manufacturer's guidelines.

Periodic calibration and plunger checks. Follow manufacturer's guidelines.

Regular tubing replacement. Follow manufacturer's guidelines.
