Five-year warranty

Demonstrating our total

confidence in reliability and our

commitment to customer satisfaction,

Watson-Marlow cased pumps in this

brochure carry a five-year warranty against faulty materials

and workmanship. It covers everything except misuse of the

pump and consumable items. Your production will not stall

because of us.

Why Watson-Marlow makes the

right pump for your process

Zero contamination

Watson-Marlow peristaltic pumps totally contain the fluid within

the tube, isolating it from any source of contamination including

he metallic components of the pump. Our high performance,

high purity tubing further enhances the integrity of the process

and provides excellent batch consistency.

Sterility

Watson-Marlow pumps have a clear straight-through flow path

eliminating possible batch contamination and downtime. Unlike

rotary lobe, diaphragm, or other pump types, there are no

crevices or dead spots that trap fluids or residue and introduce

a major source of bacterial contamination.

Confident controllability

Watson-Marlow pumps integrate

seamlessly into your process control

system. The pump is self contained and

easily configurable; there is no need for

separate variable frequency drives or

complex control devices. With built-in

manual, analogue and digital control

features, our pumps have the I/O capabilities to

meet your process control and monitoring needs.

Low shear

Watson-Marlow peristaltic pumps are low-shear, allowing you to

move product without degradation or damage. There is no need

to worry about the high velocities and arduous flow paths

associated with impellers, vanes, lobes or valves in other pump

types that can damage the product.

Accuracy

Metering or dosing of sanitary products demands accurate and

repeatable flow rates. Using microprocessor controlled

brushless DC drive technology, Watson-Marlow pumps meter

within ± 0.5% accuracy, ensuring process stability and finished

product quality.

Reliability

We know that pump failure during production cannot be

tolerated due to the intrinsic value of the product. That is why

we design our pumpheads and drives to be maintenance free

and utilise spring loaded rollers and tracks to

provide tubing with long and repeatable life.
