Stator
SEEPEX PC Pump Technology
• Cavitiy always retains the same
shape and volume
• Flow is a proportional
relationship to speed/RPM
• Constant, Pulsation-free flow
because of overlapping fluid
chambers

Water Treatment Plants?
Polymer
Why Low Shear Solution is Important
Maintaining Polymer Integrity -
• PC Pumps Exert 60-100 sec.-1 of shear
/100 rpm
• Lobe Pumps Exert ~1200 sec.-1 of shear
/100 rpm
• Gear Pumps Exert ~12,500 sec.-1 of shear
/100 rpm

• BETTER Process Control
Stable flow for precise flow measurement.
• The benefits of PC pumps enable packagers to
use flow meters that read in real time as
opposed to time buffering for pulsation on
diaphragm pumps.
• Highly accurate, but sensitive coriolis flow
meters (shown below) require stable flow.
• Diaphragm pump manufacturers have to add
pulsation dampeners that cost $1000-$2000
based on pump size.
SEEPEX Chemical Pumps
Case Study in Point!
Stable flow leads to lower chemical costs!
• Seepex PCPs are highly accurate, valveless,
flow stabilizer devices. Think about it.
Instead of displacing 5 batch cycles per
minute from a hose or diaphragm pump you
can displace over 100 in smaller dosing
cavities and stabilize your flow chart (as
shown on the previous slide).
• Our pump solutions are guaranteed to
stabilize your SCADA readings in real time
with minimum variation around the set point.
Most customers find a reduction in chemical
usage immediately in which the pump
provides an ROI in just months.

Yellow line is water from a vertical turbine.
Blue line is Sodium Hypochlorite.

Hysteresis
• Eliminating the control valve eliminates hysteresis.
• The PC pump curve is more stable.
