are completely self-priming, positive-displacement pumps with no
check valves or components in the fluid stream.The only material
the fluid touches is the tubing itself. Rated for continuous duty
and useable from -100 to 120 C, these pumps can handle liquids,gases and
slurries at pressure upto15 psi for gases and 40 psi for liquids. They
pull vacuums upto 24" Hg. Simply run a length of tubing from your
reservoir, through the pump head and into your receiving container with
no valves or fitting in the way. Because the tubing can be sterilised,
the Peristaltic Pump is the ideal system for sterile and other sensitive
precision pumping situations.
EEC Peristaltic System consists of three parts :
the pump head;
the Pump Controller and
the tubing itself.
variety of pumps are available to suit every application. Flow rate range
is from 0.1mL/Hr to 100 L/Hr.
offers FIVE MODELS OF PERISTALTIC PUMPS
The 2-Roller Head is made of polypropelene and has a steel
rotor, 2 stainless- steel ball bearings and 2 Silicone coated rollers.
It accepts tubing from 1 to 4 mm bore of 1.5mm wall thickness. The
3-Roller Head is made of aluminium and has a steel rotor, 8 stainless
-steel ball bearings and 3 aluminium rollers. The 3-Roller pump is specially
designed to reduce pulsations and give a smoother, more uniform
flow pattern. The Pump Heads are driven with precision stepper Motors
or D.C. Motors.They accept any tubing from 1 to 7mm bore of 1.5mm
Controller : A 3-Digit LED Digital
Display indicates the pump speed/flow rate. The display reading
can be adjusted by soft-touch Increase/Decrease keyboard switches from
0.1 to 100, in steps of 0.1; and from 100 to 500 in steps of
1. Thus the total flow range with each tubing size can be varied
from minimum to maximum in 1400 steps. The timer can be programmed
to operate the pump for any set period from 1 minute to 24 Hours,
in steps of 1 minute.
Thumbwheel Controller : A
2-Digit Thumbswitch is used to set the Pump speed/rate. The total flow
range with each tubing size, can be adjusted from minimum to maximum from
1 to 99, i.e. in 99 steps.
Controller : A
10-turn Potentiometer is used to vary the flow rate from the minimum to
maximum. A digital display indicates the speed/flow rate.
