Five-year warranty
Demonstrating our total confidence in
reliability and our commitment to customer
satisfaction, Watson-Marlow Bredel 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 Bredel makes
the right pump for your process
Unbeatable turndown
With a 3600:1 control ratio and over a million:1 flow range, one
Watson-Marlow Bredel pump can do the work of several lobe or
diaphragm pumps. They handle a range of flow rates unmatched
in the pump industry.
Vapor lock eliminated
When pumping mixed phase liquids like sodium hypochlorite, lobe
and diaphragm pumps can vapor lock when the gas enters the
pump chamber. Watson-Marlow Bredel pumps handle the gas as
easily as liquid, eliminating the risk of vapor lock.
Chemical resistance
Inside and out, Watson-Marlow Bredel pumps stand up to today’s
most aggressive chemicals. NEMA 4X washdown enclosures
ensure long pump life even in the toughest industrial
environments. In addition, our wide range of
tube element materials guarantee chemical
compatibility with your fluid.
Confident controllability
Watson-Marlow Bredel 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, analog and
digital control features, our pumps have the I/O capabilities to
meet your process control and monitoring needs.
Self-priming and dry-running
It is not always possible to position a pump in the ideal location
and often self-priming and dry-running performance is required.
These conditions will cause wear in traditional pumps, resulting in
loss of performance and premature failure. Watson-Marlow Bredel
pumps can dry prime up to 30 feet and run dry indefinitely.
Unmatched accuracy
Using microprocessor controlled brushless DC drive technology,
Watson-Marlow Bredel pumps meter within ± 0.5% accuracy,
regardless of fluid viscosity changes ensuring economical use of
expensive chemicals, correct system performance and finished
product quality.
Lowest life cycle cost
Leakage, clogging or blockage of pumps designed
with seals, valves, lobes, rotors, pistons or vanes
can be a regular occurrence and expensive to
repair. Watson-Marlow Bredel pumps contain
the fluid in a low cost tube element, that takes
only minutes to replace. We also help save
on capital and maintenance cost by not
requiring ancillary equipment.
