Product description

gamma/ X – the proven best-seller intelligently extended

The new solenoid-driven metering pump gamma/ X is user-friendly and has a long service life, just like its predecessor. An ingenious solenoid control measures the pending back pressure and protects the system from overload. This technology makes a pressure sensor superfluous, meaning that operating safety can be significantly increased: no additional parts come into contact with the feed chemical, there are no additional sealing surfaces and no electronic components come near the feed chemical.

Whether the metering volume fluctuates or hydraulic failures affect the metering process – the gamma/ X allows you to keep an eye on everything.

It independently ensures a trouble-free metering process and, should the pump ever need maintenance, its service module draws attention to this.

Your benefits

Simple adjustment of the metering rate directly in l/h
In concentration mode, direct input of the required and desired concentration during volume-proportional metering tasks
Integrated pressure measurement and display for greater safety during commissioning and in the process
Control range for metering rate 1:40,000
Virtually wear-free solenoid drive, overload-proof and economical
Suitable for continuous micro-metering from approx. 1 ml/h, thanks to the regulated solenoid drive

Passing the test: consistent 100% accuracy in fluid metering

Our reliable metering pumps produce impressive results in testing. They meter fluids precisely and continuously, making it easy to optimise process parameters.

Metering of Fluids in Chemical Production

Incredible versatility: metering pumps in production

There are various types of metering pumps, but what they all have in common is reliability, robustness and thoroughness. That's why all our pumps are in demand in chemical production.

Metering Chemicals in Coolant Treatment

The secret of a highly durable coolant system

We treat coolants with small quantities of chemicals, reducing the environmental footprint while protecting the system against corrosion, deposits and biological growth.

Addition of Additives in the Paper and Pulp Industry

Lighter, smoother, more solid? The right addition is key

Not all paper is the same. Accurately metered additives reliably give the paper certain properties, such as making it whiter or smoother or indeed both. ProMinent is fully flexible.

Waste Water Treatment in the Paper and Pulp Industry

Clean waste water is returned to nature

Very low-impact treatment for waste water. Our intelligent processes efficiently clean and save money too.

Biocide Metering in the Paper and Pulp Industry

No clumps formed in the production of paper

Perfectly metered liquid biocides prevent the formation of slime and therefore the dreaded and expensive formation of clumps in paper machines. So operations can continue unaffected.

Potable Water Treatment

Outstanding water quality in line with global WHO standards

ProMinent turns water into hygienically perfect potable water – with powerful systems and components, which can be ready mounted for operation or individually configured.

Flotation in Mining

Frothers and collecting agents

To remove ore from the flotation liquid faster, activating chemicals (frothers and collecting agents) have to be accurately added by metering. Getting the right amounts is crucial.

Electrolytic Metal Extraction in Mining

Off you go - metering systems ready to use immediately

Do you need a quick metering solution? Our complete mining systems come fully ready mounted and are installed in no time. Tailored to the customer, they deliver excellent storage and metering results.

Our chemically resistant material versions are ideal for solvent extraction. The materials will withstand harsh chemicals and costly repairs don't arise.

Water Softening in Public Swimming Pools

Water softening is a key element of water treatment

Water softening is a key element of water treatment for public swimming pools. Soft water reduces the likelihood of operating system failure and ensures that the pool attractions look their very best.

Flocculation in Public Swimming Pools

Metering flocculants delivers optimum filtration

Flocculants allow the smallest of particles to be removed from the swimming pool water. In turn, our high-precision solenoid metering pumps enable the precise and continuous supply of small volumes of these flocculants.

Internal Water Management in Hotels and Resorts

The best water for your kitchens and laundry

Fresh bedding and sweet-smelling towels in rooms, spotlessly clean dishes and fine dining in the restaurant – desalinated and germ-free water is absolutely essential. You have the staff, we have the system technology.

It can be disastrous for any hotel if guests come down with legionella and seek claims for damages from the company. ProMinent provides effective solutions for eliminating legionella and other pathogens in the long term.

Swimming Pool Water Treatment in Hotels and Resorts

Absolutely essential: an attractive pool with crystal-clear water

You are an expert in pampering your guests, young and old, with everything they could desire. This usually includes an attractive swimming pool or even a luxurious spa. This is where one of our core skills come in.

Potable Water Supply in Hotels and Resorts

Only the best for your guests: clean potable water around the clock

Clean potable water is a basic requirement for guest satisfaction and therefore commercial success. ProMinent's treatment systems enable you to provide outstanding quality water all year round.

(Pre-)Oxidation of Potable Water

(Pre-)oxidation binds harmful substances in potable water

(Pre-)oxidation improves water quality by eliminating many harmful substances and improving appearance, odour and taste. No one wants to drink brown water.

(Sand) Filtration for Potable Water

Filtration removes solids from the water

Unwanted particles and turbidity are removed from the water by sand or membrane filtration. An even more effective process is to filter using upstream flocculation or precipitation. Added substances allow smaller particles to become larger, so dissolved substances can flocculate.

Desalination of Seawater and Brackish Water

Obtaining additional potable water with desalination

Drinkable water is scarce. Only a fraction of all the world's water can be consumed. So the ability to treat brackish water and seawater is of interest to many countries and islands.

Stabilisation of Potable Water

Stabilisation makes water ready for transport

After the water has been treated, its quality should not change. Stabilisation maintains the quality of the water during distribution and use.

Disinfection of Potable Water

Germ-free potable water thanks to disinfection

As an essential nutrient, water must satisfy very strict quality controls. ProMinent offers sophisticated disinfection technology that reliably removes viruses, bacteria and microorganisms.
