Portable Battery-Powered Peristaltic Pump

What is the Portable Battery-Powered Peristaltic Pump?

A portable battery-powered peristaltic pump runs on rechargeable batteries for field sampling, in-cabinet work and locations without mains power. It provides the same tubing-based fluid handling in a compact, self-contained portable package.

Overview

The portable peristaltic pump uses a compact brushless DC motor powered by a lithium-ion or nickel-metal-hydride battery. Flow ranges from a few milliliters to about 2 L per minute with tubing up to 8 mm bore, and a single charge typically lasts several hours. Battery status, speed and sometimes volume are shown on a small display. Because the pump needs no mains connection, it suits water and wastewater sampling in the field, ground and surface water collection, ventilation and duct sampling, and use inside cabinets where cables would be inconvenient. The pump is self-priming and can lift water from a depth depending on tubing and battery power. A removable pump head or a protective case makes transport and cleaning easier, and it can often be powered from a car socket or external pack for longer campaigns.

How does it work?

A peristaltic pump has a rotor carrying two or more rollers that press the tubing against a curved raceway. As the rotor turns, the rollers occlude the tube and push a trapped volume of liquid forward, while the tube behind the roller recovers and draws in more fluid. The displaced volume per revolution depends on the tube bore and wall, so flow is set by tube size and rotation speed. Because the fluid stays inside the tubing, the pump head never touches the sample, giving excellent chemical compatibility and making sterilization simple: replace the tubing or use pre-sterilized sets. Flow is nearly pulseless at higher speeds but slightly pulsed at low speeds and with few rollers. Typical components are the drive motor, pump head, tubing, and a control interface for speed, direction and sometimes calibration.

What are the key features?

• Rechargeable lithium-ion or NiMH battery pack
• Flow of a few mL/min to about 2 L/min
• Runtime of several hours per charge
• Self-priming with depth lift capability
• Compact and transportable with protective case
• External power option for extended use

What are the technical specifications?

A typical portable battery-powered peristaltic pump configuration offers flow range of 0.001–2,000 mL/min, tubing sizes of 3–8 mm inner diameter, suction lift of Up to about 8 m water, battery type of Rechargeable lithium-ion or NiMH, runtime per charge of 3–8 h typical and charge time of 3–6 h. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Portable Battery-Powered Peristaltic Pump is used in field water and wastewater sampling, groundwater and surface water collection, duct and stack sampling, in-cabinet fluid handling and emergency and remote-site transfer. Across the wider Peristaltic Pumps class, laboratories also deploy it for sterile media and buffer transfer, reagent dosing and metering and continuous flow chemistry.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, IEC 61326-1, ISO 9001, USP <87>, USP <88> and GB 4793.1. Certification candidates for this model are CE, RoHS and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Tubing is the main consumable and also the calibration reference, so keep the same part number and replace it on a schedule or when flow drifts. Recalibrate after changing tubing, since wall thickness and elasticity affect volume per revolution. Avoid over-tightening the pump head, which shortens tube life, and do not run dry for long periods unless the tubing is rated for it. Keep the raceway and rollers clean, and check for wear that causes uneven flow. For sterile or hazardous liquids, work inside a biosafety cabinet and use closed tubing sets. Follow IEC 61010-1 for electrical safety. In flow chemistry and metering applications, verify against a balance or flow meter, and record tubing lot and calibration data so results remain traceable.

How do I select the right Portable Battery-Powered Peristaltic Pump?

Choose a battery-powered pump for field, remote or cable-free work. For fixed benchtop use a mains pump costs less and gives higher flow. In the RFQ, state flow and lift, tubing size, runtime needed, protection rating and whether an external power or car adapter is required.

How does it compare with other Peristaltic Pumps variants?

Start with flow range and tubing size. Small-bore tubing gives microliter flows for microfluidics and dosing, while large-bore tubing moves liters per minute for media transfer and process work. Confirm the tubing material for chemical compatibility and temperature: silicone is flexible and autoclavable, while PharMed or Viton resist solvents and high temperatures. Decide whether you need a single channel or several channels running in parallel, and whether channel-to-channel accuracy matters. Choose the drive for speed range, torque and control features such as dispensing, ramp profiles, remote control and data output. For sterile work, look for autoclavable or disposable tubing sets and quick-release heads. Consider pulsation where smooth flow is important, since more rollers and higher speeds reduce it. Add calibration to convert speed into a reliable volume.
