Product group D.
D Dosing pumps
The 6 ranges of dosing pumps can be used in virtually all
industries for the metering and dosing of precise quantities.
They are particularly good for low-pulsation conveying of
low to high viscosity fluids, as well as media containing
solids and those that are chemically aggressive.
Stator adapter
in stainless steel, enabling the use of
all sizes of rotor/stator giving interchangeability with only one housing
and drive unit.
Rotor
wear resistant and corrosion-proof
materials.
Tie rods and screw connections
in stainless steel.
Suction casing
in stainless steel, 1" connection to DIN EN ISO 228-1
or NPT, can be rotated in 90 increments, with drain
plug, available with gauge or flushing connections.
Pressure branch
in stainless steel, 1/2" connections to
DIN EN ISO 228-1or NPT.
Stator
the seal on both ends is moulded as an integral part of the
elastomeric stator; corrosion of the stator tube is never
a problem because the pumped liquid never comes into
contact with the metal tube or the bonding adhesive.
Plug-in shaft connection
for easy dismantling of the pump and drive
enabling quick replacement of the rotating parts
and shaft seals. The plug-in shaft pin secures
the shaft connection to the drive and the splash
ring protects the bearing from contamination /
gland leakage.
Shaft seal
single acting mechanical seal. Alternatively, a double acting
mechanical seal or gland packing are available.
Coupling rod
with two pin joints with hardened
and wear resistant components,
easily assembled, grease lubricated
and positively sealed with elastomer
sleeves and two holding bands.
Drive
geared motors, variable speed drives or
hydraulic motors of all major manufacturers, directly flanged to the pump
without additional couplings or guards.
Lantern
for connection of pump and drive.
Plug-in shaft
connects the drive shaft to the joint; with gland
packing the plug-in shaft is used as a shaft protection
sleeve.
Why dosing pumps?
Because they are used in applications such as agriculture,
automotive industry, ceramics industry, construction, brewing
industry and distilleries, chemical and biochemical industry,
coating kitchen, confectionery industry, dough processing
and bakeries, drinking water treatment, dyeing and varnishing industry, fruit and vegetable processing, metering of
chemical additives, milk and dairy industry, paper machine,
pharmaceutical and cosmetics industry, poultry and meat
processing, oil, gas and petrochemical industry, shipbuilding, sludge dewatering, stock preparation, supply industry,
textile industry, waste water and sludge treatment, wine
industry and wood processing.
Features
Simple interchangeability due to their modular construction
Low pulsation, no pulsation dampeners required
High metering accuracy (deviation 1%)
Constant flow, independent of pressure
Eliminates control valves
No ball valves to clog

Overview of ranges
Apart from a stainless steel housing, pumps of the MD range
are also available with housing parts made of plastic. In
combination with components made of Hastelloy C (2.4610)
or Titan (3.7035) that come into contact with fluids, these
pumps are especially well suited for pumping and dosing
chemically aggressive media.
Range MD
The pumps of the MDP range are available with stainless
steel or plastic housing. A special feature is the patented,
one-piece, wear resistant plastic rotating unit without joint.
In connection with PTFE stators, these pumps can be used
for pumping and dosing media containing hydrocarbon such
as paints, varnishes, solvents, diluents and the like for the
first time.
Range MDP
Overview of ranges
The pumps of the MDT range feature a feed hopper with a
cylindrical compression zone. Conveying media with a low
degree of intrinsic flowability or with none at all are fed to
the conveying elements rotor and stator through the auger
feed screw on the coupling rod. Optimum filling of the conveying chamber is achieved through the priming pressure
generated in the compression zone.
Range MDT
The pumps of the MDC range are equipped with open
hygienic fork joints that can be cleaned almost without leaving
residues through CIP continuous cleaning. They meet highest
demands on hygienic cleanliness and on corrosion and wear
resistance. This is achieved through the special shape of
the rotor/plug-in shaft coupling rod head. Since the open
joint is made up of only a few components, service work
can be performed easily and rapidly without the need for
special tools. They are certified acc. to the 3-A Sanitary
Standard of the US and designed in compliance with the
EHEDG directives.
Range MDC
The MDTC range features a feed hopper with a cylindrical/
conical compression zone. Conveying media with a low
degree of intrinsic flowability or with none at all are fed to
the conveying elements rotor and stator through the auger
feed screw on the coupling rod. Optimum filling of the conveying chamber is achieved through the priming pressure
generated in the compression zone. The pumps of the MDTC
range are equipped with open joints of the MDC range.
They are certified acc. to the 3-A Sanitary Standard of the
US and designed in compliance with the EHEDG directives.
Range MDTC
Pumps of the MDF range are used as barrel pumps for draining barrels open or closed on top with 2" faucet holes.
The supply pressure on the suction side also facilitates
trouble-free draining of barrels with low-viscous to highly
viscous media. The pump is easy to transport through a
handle attached to the lantern.
