- 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 574 litres/hr
- Pressures up to 10
bar (145 psi)
- Suitable for water
treatment and petrochemical applications
Technical Features
All pumps are fitted as standard with gearbox
reduction system and with vertically mounted V18 shaped electric
motor that conform to the UNEL-MEC specifications. The motor's
power range is from 0.18 kW up to 0.25 kW at European standard
3 phase voltages of 230/400V @ 50Hz, 4 poles.
The motors conform to the UNEL-MEC specifications and
are available with different
voltages, frequencies, insulation standards and special explosion
proof versions.
The gearbox utilises a worm-wheel reduction
system with all bearings fully supported within the fully lubricated
gearbox.
The manually adjustable output with spring
return is operated by micrometer type stroke limiter, which adjusts the piston
delivery stroke (output), while the suction stroke (reload) is
spring assisted.
Capacity adjustment can be effected whilst
in operation or at rest. The movement of the piston is controlled by a precise reciprocating gearbox which
ensures an accurate and repeatable volumetric
displacement.
Automatic remote flow
control adjustment
is also available by means of servo control units, with 4-20mA
control signal, or by means of a 3 - 15 psi pneumatic control signal.
The simple build configuration and a
small number of component parts allow an easy checking and maintenance.

Product Code Description
D series Mechanical Diaphragm pumps are
available in four different sizes:
D 050 N - Max 49 Ltrs/hr
D 100 N - Max 374 Ltrs/hr
D 101 N - Max 408 Ltrs/hr
D 121 N - Max 574 Ltrs/hr
|
|
For these two types 4 different diaphragm
sizes are available to suit each clients'
applications for capacity and pressure.
Mechanical diaphragm metering pumps are
suitable for use when:
The dosed liquid contains small amounts of solids in suspension.
The dosed liquid is a toxic solution.
A drip proof/air tight application is required.
High pressure dosing is not required
Standard materials of pump-head
construction:
AISI 316 Stainless steel and PVC.
Available in many different materials of
construction to suit the chemicals in use.
Jacketed pump-heads for either cooling or
heating are available to suit requirements. Valves
Heads
All pumps
are fitted as standard with gearbox reduction system and with
vertically mounted V18 shaped electric motor that conform to
the UNEL-MEC specifications.
The motor's power range is from 0.18 kW up to 0.55 kW at European
standard 3 phase voltages of 230/400V @ 50Hz, 4 poles.
Multiple
Headed Pumps
Different multiple
heads units are available on request.
Each pumping element is independently adjustable both in operation
or at rest.
