Makro TZ Plunger metering pump

The motor-driven packed-plunger metering pump Makro/TZ because of its modular design is excellently suited to being adapted to the performance requirements of the particular application. A great variety of options are available for its operation, either one or two liquid ends and one or several add-on pumps which the customer can fit at a later stage.

Advantages

High processing quality: Repeatability of dosage better than ± 0.5 %
Broad field of application, easily adapted even by the customer due to its modular design

Application Areas

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

Features

Performance range for the single pump: 2.4 - 301 gph (9 – 1,141 L/h), 4,641 - 159 psig (320 - 11 bar)
Supplied as a single or dual-headed version
Push-pull operation of the liquid ends with dual head designs
Can be easily upgraded to a triple pump at a reduced back pressure to more pumps even on the customer’s premises
Independent of the main metering pump, other stroke counts can be achieved with the add-on pumps, as each TZ add-on pump has its own reducing gear
Standard drive: Dual wound three-phase motor 230/400 V, 50/60 Hz, 0.75 or 1.5 kW (2.2 kW or 3 kW also available as options) enclosure class rated IP 55 (optional ATEX-T3/T4), insulation class F
Gearing in 4 optional reduction ratios
Stroke length: 0 to 0.78" (0 - 20 mm) and adjustable to 0.5 % precision using a gyrating cylinder
Stroke length setting: manual (optional with actuator or variable speed drive)
Gear housing: Cast iron, resistant to seawater, acrylic resin lacquer finish
Liquid end materials: Stainless steel
Metering plungers in oxide ceramic or stainless steel with ceramic coating for protection against wear
Reproducibility of metering 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 pipes and the number of strokes
