Makro/ 5 Hydraulic Diaphragm Metering Pump

Application Areas

• Metering of reactant and catalysts in the chemical industry
• Time-controlled metering of chemicals for the regeneration of ion exchangers
• General application in industrial process technologies, e.g. when mixing drilling emulsion as adjuvant to chipping machine tools

Features

• Drive unit is designed for the operation of two liquid ends with a capacity of 2 x 1,585 gph (6,000 L/h)
• Extensible to 10,567 gph (40,000 L/h) through up to three mounted pumps, at reduced counter-pressure up to 4 mounted pumps (use of a mounting frame necessary)
• Counter-pressure 87 - 362 psig (6 - 25 bar)
• With double-head-version M5HaD (main pump) and M5HaB (mounted pump) the liquid ends are operated in push-pull-technology
• Standard drive: spur gear motor 3 kW (optionally 5.5 kW), 230/400 V, 50/60 Hz, protection class IP 55 (optionally ATEX-T3/T4), Isolation class F
• Stroke length adjustment 0 - 1.9" (0 - 50 mm)
• Stroke length adjustment: manually (optionally with variable speed drive)
• Optional frequency converter for speed control, protection class IP 54, with evaluator for the temperature control of the motor
• Optional stroke sensor with Namur-signal for the registration of each metering stroke, suitable for charge metering or proportional metering.
• Gear housing: cast, seawater resistant, acrylic resin coated
• Liquid end materials: Polypropylene, PVC, PTFE with carbon, stainless steel
• Reproducibility of metering at defined conditions and correct installation better +/- 1 % (stroke length range 10 - 100%)
• Suction lift varying with density and viscosity of medium as well as connection pipework and the stroke number
