Pumps and Systems<br />
Peristaltic pumps<br />
tive. They found what they were looking<br />
for with the peristaltic metering<br />
pumps from Watson-Marlow Fluid<br />
<strong>Technology</strong> Solutions.<br />
Peristaltic metering pumps for<br />
water treatment<br />
Fig. 4: A total of five pumps have been in use in the dosing station for flocculants for more<br />
than a year.<br />
The decision was made to initially test<br />
Qdos as part of a six-month field trial<br />
- first with a certain amount of scepticism.<br />
“At that time, I was mainly familiar<br />
with peristaltic pumps as a solution<br />
for sterile applications in medical<br />
technology and pharmaceuticals, but<br />
not as a metering solution for the water<br />
industry,” reports the engineer.<br />
“I was therefore initially unsure about<br />
the cost-effectiveness of peristaltic<br />
pumps in water treatment. Especially<br />
as peristaltic pumps are somewhat<br />
more expensive to purchase.”<br />
The peristaltic pump from<br />
Watson-Marlow was developed specifically<br />
for metering chemicals and<br />
treatment substances in the water industry.<br />
“As a peristaltic pump, Qdos<br />
has no diaphragms, valves or seals to<br />
clog or leak. As a result, it offers particularly<br />
low installation costs and<br />
can be easily installed in existing metering<br />
systems to replace previously<br />
used pumps without additional equipment,”<br />
explains the Sales Engineer at<br />
Watson-Marlow.<br />
In addition, the peristaltic metering<br />
pump has a particularly innovative<br />
design principle: the only wearing<br />
part on the entire pump is the<br />
patented ReNu pumphead, which can<br />
be replaced as a single component in<br />
just a few minutes. The pump is then<br />
available “as new”. As the pumphead<br />
is completely encapsulated, any leakage<br />
of liquid is reliably prevented.<br />
The operator does not come into contact<br />
with the pumped liquid.<br />
Wide range of sizes, pump head<br />
and control options<br />
The versatile Qdos metering pumps<br />
are used in countless applications in<br />
the water and wastewater industry,<br />
