Makro/ 5 Plunger Metering Pump

The motor-driven plunger metering pump Makro/5 is characterised by its modular design for add-ons. With the option of one or two liquid ends and one or several add-on pumps, its performance can be enhanced up to a maximum of 20,000 l/h.

Advantages

High processing reliability: Powerful, reliable and extremely robust
High processing quality: Reproducibility of dosage better than ±0.5 %
Broad field of application, easily adapted later even by the customer because of its modular design.

Areas of application

Dosing of treatment agents in industrial production technology
Dosing of additives in the chemical and petrochemical industry, e.g. dosing of glycol in the delivery of natural gas

Features

The drive unit is designed for operating two liquid ends with an output of 2 x 6,000 l/h
Can be increased to 20,000 l/h by adding up to three add-on pumps, and with reduced back pressure up to four add-on pumps (the use of an installation frame is necessary).
Back pressure 6 – 320 bar
Push-pull operation of the liquid ends with dual head designs
Standard drive: Dual wound three-phase motor 3 kW (optional 5.5 KW), 230/400 V, 50/60 Hz, enclosure class rated IP 55 (optional ATEX-T3/T4), insulation class F
Stroke displacement 0-50 mm
Stroke length setting: manual (optional with variable speed drive)
Optional electronic frequency converter for speed control, enclosure class rated IP54, with monitor for monitoring the temperature of the motor
Optional stroke sensor with NAMUR signal for exact recording of each dosing stroke, suitable for batch dosing or proportional dosing
Gear housing: Cast iron, resistant to seawater, acrylic resin lacquer finish
Plunger liquid ends made of stainless steel 1.4571
Ceramic oxide ceramic or stainless steel plungers with ceramic coating for protection against wear
Reproducibility of dosing better under defined conditions and correct installation ± 0.5 % (stroke length 10-100%)
Suction lift varies with density and viscosity of the medium as well as the connecting pipework and the number of strokes
