- Manually adjustable
output with spring return function
- Suitable for use with
abrasive liquids with small amounts of solids in suspension for all drip
proof / airtight applications
- Available in many
different materials of construction including PVC, PTFE, PVDF and
Stainless Steel to suit most chemicals
- Output capacities up
to 47 litres/hr
- Pressures up to 10
bar (145 psi)
- Suitable for water
treatment and petrochemical applications
Technical Features
Adjustable capacity from 0-l00% whilst
in operation or at rest.
The movement of the diaphragm is based on a precise reciprocating
gearbox which provides for exact volumetric displacement.
Exact diaphragm movement is achieved, thereby providing accurate
stroke reproduction. Linear capacity
is achieved, at all stroke settings.
The gearbox mechanism is operated by an eccentric cam, which
offers a positive displacement delivery stroke, whilst
the suction stroke is spring assisted. Vertically mounted motors
are fitted to the chemical dosing pump and the gearbox 0.09 kW.
Both single and three phase motors can be fitted to suit site
requirements.
The gearbox utilises a worm-wheel reduction system with all
bearings fully immersed within the grease lubrication.
Specifications
4 sizes of gearbox are available offering
stroke movements from 0-5 mm.
Maximum suction lift of 2 metres.
Operating temperatures minimum 0° C - maximum 50°C.
Metering Pump Heads
The pump-head is connected to the gearbox
via a spacer assembly.
The pump-heads utilise mechanically actuated diaphragm.
Double valve ball assemblies are available which have been designed
for easy inspection and accessibility.
Suction and delivery connections, if requested, can be 3/8"

(*1) Piston's strokes number during 1 minute with 4 poles installed
motor
H = Reducer ratio 1 : 34 = 41 strokes at 50 Hz / 49 strokes
at 60 Hz
F = Reducer ratio 1 : 24 = 58 strokes at 50 Hz / 70 strokes
at 60 Hz
D = Reducer ratio 1 : 17 = 82 strokes at 50 Hz / 98 strokes
at 60 Hz
B = Reducer ratio 1 : 12 = 116 strokes at 50 Hz
(*2) The indicated capacity value is subject to changes due to
the working pressure, the dosed liquid, the viscosity and the
installation asset.
(*3) Higher pressures are available with out of standard executions.
(*4) If requested, different range of connections are available.
(*5) The weight is approximate and is the value of the pump fitted
with a totally enclosed fan- cooled outdoor motor.
(6) The pumps can be supplied with accessories if requested.
(7) The pumps are painted with a 2 part EPOXY-POLYAMIDE PAINT
RAL 7030. |
