Diaphragm Metering Pumps
Not just sealed, hermetically sealed!
The hermetically sealed metering units and resistant materials of ProMinent diaphragm process metering pumps enable them to pump aggressive media with ease. But that’s not all because maintenance-free and fault-free operation also depends on the quality of the diaphragm, which is why ProMinent always ensures that its products are equipped with extremely durable diaphragms.
Strong diaphragms, sealed metering units and resistant materials make just the right combination in oil/gas production (onshore/offshore), refineries, and the chemical / petrochemical, pharmaceutical, cosmetics and food production industries. We recommend special ProMinent metering pumps for the process industry.
The micrometre adjustment dial for the stroke length guarantees precise adjustments and high reproducibility. Compensation means that the pump is operated reliably even during fluctuations in mains voltage. Different control types make easy process integration possible. The dosing head is self-bleeding, which also makes it suitable for outgassing media.
ProMinent always holds a wide range of pump accessories in stock. Our principle is that ProMinent pumps can be extended, are flexibly adaptable and modular. The pump should fit your requirements, not the other way round.
The choice of pumps is huge: 80 industries, 100,000 products and infinite applications. To make it easy to find your ideal metering pump, ProMinent designed the Pump Guide. In just a few clicks you will find a selection of suitable models.
Here’s how it works
First enter the pump capacity and back pressure. The Pump Guide will then show you all the metering pumps that match your criteria. You can choose between list view and detail view. The database contains all solenoid metering pumps, motor-driven metering pumps, process metering pumps and peristaltic pumps from ProMinent. They are divided into more than 30 different product ranges.
Exactly the right pump
Narrow down your search by clicking on different selection criteria. Do you have a specific industry, operating mode, medium or viscosity in mind? Or maybe you need a pump for zones at risk of explosion? The Pump Guide will take you to the pump you need in just a few clicks.
Diaphragm Metering Pump ProMinent EXTRONIC
Capacity range of single head pump: 1 – 60 l/h; 25 – 1 bar
The diaphragm metering pump EXTRONIC is perfectly suited to the sensitive application of liquid media in facilities at risk of gas explosions as it is approved in compliance with the EU EX Regulation 2014/34/EU (ATEX). more
Optimum adaptation for use in areas at risk from explosion
- ATEX-compliant in line with EExd IIC T6 and EExd I/IIC T6
- Excellent operating and functional reliability by a microprocessor controller, which compensates for fluctuations in mains voltage and automatically switches from 50 to 60 Hz operation
- Broad range of applications due to operating voltages of 230 V, 115 V, special voltage on request
- Ease of integration into processes, thanks to the range of control types (internal, external contact, analogue)
- Also suitable for use with gaseous media, thanks to the self-bleeding head
Diaphragm metering pump Makro TZ
Capacity range of single head pump: 260 – 2,100 l/h, 12 – 4 bar
The modular construction of the diaphragm metering pump MAKRO TZMb with adjustable eccentric drive mechanism and mechanically deflected multi-layer safety diaphragm enables it to be outstandingly adapted to the performance requirements of the respective application. more
Excellent process safety and reliability:
