SEEPEX PC Pump Technology

Rotor turning within the

Stator


• 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


Cavities

Laminar, Pulse Free, Low Shear

SEEPEX Polymer Pumps

Where do you find PC pumps in Water and Waste

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

SEEPEX Chemical Pumps

Non Pulsating

• No Pulsation Dampeners

• No Back Pressure Valves Required

• Accurate & Precise Metering

• Do Not Vapor Lock

• Handle Abrasives

• 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.

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.

after (seepex PC) at a bottling plant.

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.
