Peristaltic pumps work straight from the box

Two new liquid pump systems include everything needed to get started.

Two new liquid pump systems include everything needed to get started.

The models 3100 and 3200 each come with 7.6m of general PVC tubing to connect the pump to its application, six precision silicone tubing cartridge assemblies (two each of 1.6, 3.2 and 4.8mm), the pump and pump head.

Out of the box and ready for action, Welch's peristaltic systems are virtually maintenance free (except for changing tubing).

Models 3100 and 3200 peristaltic pump systems have no seals or valves that can leak.

The systems are able to run dry, self-priming, and sterilisable.

Loaded with several key features, Welch's peristaltic systems are equipped with everything required: a bidirectional (reversible) flow control potentiometer (model 3100) and switch (model 3200), maximum flow switch, a universal electrical design (90 to 230V, 50/60 Hz), stackable up to three units, flow rates from 3 to 300ml/min at 200rev/min, and a true digital speed display on model 3200.

Designed with today's end users in mind, Welch's Lok-n-Flow head and cartridge assembly design makes changing tubing easy.

First, untwist the head's locking mechanism, then replace the tube cartridge, and finally snap the lock back into place.

There is no need to look for keys or cut new tubing to length.

With Welch's Lok-n-Flow cartridge assembly users are up and running in seconds.

Chemically compatible to meet all application requirements, Welch brand tubing, Lok-n-Flow cartridge assemblies, fittings and quick-connects accessories are made of the highest quality materials: Silicone, Santoprene rubber, PVC, Viton, Kynar, polyethylene and nylon.
