HemiTor™ Pump System
Single Use, Pulse Free
A Positive Displacement, Single Use, Full Vacuum pump head for use in any circulated fluid application
where pulsation needs to be minimized and prevention of cross-contamination of pumped fluids is
critical.
Is your fluid path sensitive to pulsation or cross-contamination? Many UF/DF
(ultrafiltration/diafiltration), culture media, and bioreactor perfusion applications are sensitive to the
pulsation from peristaltic pumps. Even at low RPM, peristaltic pump operation can lead to undesirable
foaming, bubbles, and cell shear.
The HemiTor™ pump system is a groundbreaking new product for the manufacturing and bioprocess lab
that enables a completely integrated, disposable flow-path, liquid handling system that is pulse-free,
spallation-free, and single-use. Bags, filters, and tubing assemblies can now be self-driven, pre-
sterilized, and completely disposable. For the first time, an affordable, completely single-use fluid path
is within reach for your tangential flow, mixing, or bioreactor system!
The HemiTor™ pump system replaces the conventional peristaltic pump head for almost every pump
application.

Piranha Color Systems
Overview
Thank you for using Piranha’s HemiTor Precision Pump for your important applications. The
HemiTor Precision Pump System delivers Precision, Versatility and Efficiency.
Piranha Color Systems proudly introduces the revolutionary HemiTor Precision Pump System. It
is a positive displacement fluid pump for precise dispensing of varying viscosity liquids as well
as for critical Life Sciences applications. The innovative pump system utilizes a novel single-use
cassette with internal dampening for precise fluid delivery and engineered for ease of use.
The HemiTor Precision Pump can be used for many different fluid transfer applications. The
basic functions are as follows:
•Accurately Dispenses by weight and volume
•Continuous Flow Rate mode
•Timed Flow Rate/Dispense mode
•Simple / universal tubing size
•Fluid Flow Pulse Dampening –Input and Output
•Unique software, easy to update for different customer requirements
Features
•The HemiTor Patented Single-Use cassette features internal pulse dampening,
minimizing product shear
•Fully programmable and customizable, advanced controller with ethernet, USB
and serial port connectivity.
•RPM operating range from 1 –1500 RPM
•Max. operating pressure 30 PSI
•Capable of pumping low to mid viscosity liquids
•Pump delivery flow rates from 0.025 mL/min to 4 L/min
•Easy to install, Single-Use pump cassette isolates the fluid path, eliminates cross
contamination and dampens pulsation.
