Makro TZ Hydraulic Diaphragm Metering Pumps

The Makro/ TZ hydraulic diaphragm metering pump sets new standards for precision and reliable operation. This is achieved with great flexibility when it comes to performance management: A great variety of options is 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 reliability: integrated alarm signal on diaphragm rupture with excess pressure recognition, even if membrane rupture occurs, the hydraulic fluid and dosing medium remain separated thanks to the latest diaphragm technology.
High processing quality: Reproducibility of dosage better than ±-1 %
New applications: Clearly increased pressure level and dosing precision can be achieved with a diaphragm pump than ever before.
Broad field of application, easily adapted even by the customer because of its modular design.

Areas of application

Dosing of reactants and catalysts in the chemical industry
Time-controlled dosing of chemicals for ion exchange regeneration
General application in industrial production technology, e.g. dosing of drilling emulsion fluids as an agent for machine tools in shaping and chipping applications.

Features

Performance range for the single pump: 300-720 l/h / 16 bar up to 1204 l/h / 10 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 and with 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
Tried and tested power end with high versatility (4 reducing gears, variable speed control, actuator, etc.)
Standard drive: dual wound three-phase motor 230/400 V, 50/60 Hz, 1.5 kW, enclosure class rated IP 55 (optional ATEX-T3/T4), insulation class F
Worm gear in 5 optional reduction ratios as well as an adjustable crank drive via a gyrating cylinder
Stroke length: 20 mm, can be set for 0.5% precision
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: Polypropylene, PVC, PTFE with carbon, stainless steel 1.4571
Patented multilayer diaphragm, even with diaphragm rupture hydraulic fluid and dosing chemical remain separated
Virtually pressure-stable characteristic curve, similar to a plunger pump through a new concept for hydraulic power transmission on to the diaphragms
Reproducibility of dosing better under defined conditions and correct installation ± -1 % (stroke length 10-100%)
Integrated alarm signal with diaphragm rupture and excess pressure recognition
Suction lift varies with density and viscosity of the medium as well as the connecting pipework and the number of strokes
