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
