Masterflex Peristaltic Pumps

@esgdm offers a range of tubing pumps suitable for dispensing,
metering and general transfer applications. Our tubing pumps offer
flow rates as low as 0.0007 mL/min to 45 LPM and are able to generate
pressures up to 8.6 bar (125 psi).

Tubing pumps confine the media to the tubing providing you with a pump
that cannot contaminate the fluid and the fluid cannot contaminate
your pump. This contamination free pumping makes tubing pumps great
for use in high purity application including the transfer or dosing of
chemicals and additives in food, pharmaceutical and semiconductor
applications. In addition as the media is confined to the tubing a
tubing pump offers easy maintenance and reduced down time compared to
other pumping technologies.

Tubing pumps use flexible tubing to run through rollers in the pump
head. As fluid goes through the pump head, packets of fluids are
formed. Flow rate is determined by the size of the packets and the
speed of the rollers turning. By controlling the size of the tubing
and the speed of the pump head accurate metering of the media can be
achieved.

@esgdm offer tubing pumps suitable for use in labs, pilot plants,
process and OEM applications. From low cost fixed speed pumps to
advanced controlled models suitable for critical metering and
dispensing applications @esgdm is able to offer a tubing pump
solution.


Advantages for tubing pumps

The only part of a tubing pump that comes in contact with the liquid
is the tubing. This maintains the sterility of fluid and the pump
@esgdm offers over 20 tubing formulations and sizes for their tubing
pumps for excellent compatibility with a variety of liquids
Self priming - our tubing pump will draw fluid into the tubing when
starting dry, up to 8.8 m suction lift. Other pumps require user to
fill pump and suction line with fluid before use which can be
inconvenient and also create potential for hazardous spills or
contamination
Gentle pumping action - low shear - makes a tubing pump ideal for
handling cells and large proteins, as the pumping action will not
damage the content
The fluid does not contact the tubing pump so there are no parts to
clean such as valves, diaphragms, seals etc. All you have to do is
clean or replace the tubing. This easy tubing replacement means
reduced maintenance times
A tubing pump is non-siphoning which means that they prevent back flow
into the system. This promotes accuracy during dispensing
