Why GATHER pumps? With the right design of the pump as well as the selection of materials and seals according to the medium and application, we offer our customers process-reliable and durable solutions. The pump bodies of the turbine and gear pumps and the shafts are made of stainless steel, Hastelloy® or titanium, the sleeve bearings of carbon or plastics such as PEEK or PTFE. In the case of gear pumps, the gears are made of a nickel-based alloy, PEEK or PTFE (Teflon®) and can be freely combined with each other. The materials used for the gear wheel, slide bearing and shaft all have excellent tribological properties.
The use of the magnet coupling, the internal cooling system together with the high precision of all components result in a very robust design with an extremely long service life. Depending on the application (medium), the pumps operate maintenance-free. GATHER is not only a component manufacturer, but also a solution provider for design as a complete system according to customer specifications with the corresponding control loop and accessories. Special solutions are our speciality as well. This also includes the use in potentially explosive atmospheres in compliance with the ATEX directives. Our sales engineers and partners have extensive expertise and application knowledge and are your contacts. Either on-site at your premises or at our head office in Wülfrath.

As already explained under „Magnetically coupled gear pump“, the GATHER gear pump is a hermetically sealed pump. This pump was designed multifunctionally in its materials in order to be able to pump many different liquids used in the laboratory.
In addition, a drive with integrated speed control is used which is a „plug and play“ solution ready for conncetion and available from stock.
Turbine pump
-
The magnetically coupled process pump
GATHER Industrie GmbH’s magnetically coupled mini turbine pump is a modern process pump for the pulsation-free metering, conveying and circulating of water, salt solutions, acids, alkalis and solvents, amongst other things.
With four different geometrical variants, flow rates ranging from 20 l up to 3600 l per hour can be attained at differential pressures up to 5 bar (see also operating data and flow rate characteristic diagram). Similar to the gear pump, it has internal wash borings and channels for efficient cooling and fluid circulation.
The magnetic coupling ensures a contactless torque transmission from the drive to the pump shaft. It is not subject to wear and tear and is absolutely maintenance-free. Together with its established slide bearings technology and simple design, the GATHER turbine pump represents a cost-effective, robust multi-purpose pump which is extremely quiet in operation.

Overflow valves for liquids, gases and vapours
-
The GATHER overflow valves are simply designed and compact pressure limiters which offer accurate inlet pressure adjustment with easy installation and maintenance. In operation, the inlet pressure is in balance with the spring-loaded valve as soon as the preset opening pressure (in the pipeline) is reached and exceeded. The preload of the valve spring – and thus the opening pressure – can easily be adjusted from the outside. As connections, standard pipe fittings or individual connections according to customer specifications are available.
- TÜV-certified

GATHER series DBG
Flat-face quick disconnect coupling
-
GATHER’s flat-face quick disconnect couplings of the DBG series shut off on both sides and can be operated with one hand. They are designed in such a way that no liquids escape when disconnected and no air pockets enter the pipe system when connected. The design of their internal structure allows inline cleaning CIP (Cleaning in Place).
All components are sufficiently washed around, product adhesions are completely removed. The pressure drop in the quick disconnect coupling is very low, as the flushability is achieved by its inner contour which ensures a favourable flow. All seals are located on the inside, which means increased operational safety.
Dry-break, Robust and Safe for Every Application- DBG series, DN 4 to DN 65
- Over 500,000 coupling cycles
- The price cutter made of simple, alloyed steel
Flat-face sterile coupling
-
Principle: First seal, then release the flow! During the coupling process, the ring valve of the socket and the flat valve of the nipple push against each other. Before the valves release the flow, the interior is shut-off against the environment. The dead space-free design prevents air inclusions when connecting and drip losses when disconnecting.
The robust DBG series represents the top model in its market with over ½ million coupling cycles.
Flat-face tank coupling
-
Shut-off design in both sides, dry-break and capable of connecting under residual pressure
The hose couplings of the DBG SV series have self-closing shut-off valves. When disconnecting, there are no liquid leakages from the hose and container, no air or dirt enters the line system when connecting. These dry-break hose couplings offer a high degree of safety during refuelling, filling and decanting, because despite frequent coupling, environmental damage or hazards to persons due to leaking liquids are excluded. The liquids do not come into contact with the ambient air. Coupling and uncoupling is very easy and smooth, even if the lines are under residual pressure.
Hansen original
HIG Series
-
Beverage-dispense coupling
The beverage-dispense coupling is used for the water supply in kitchens, but also for the product pipes of beverages, such as lemonades and concentrates. They make in-line cleaning (CIP) and a fast connection process possible.
HK Series
-
Double shut-off design
(single shut-off or in both halves possible)The quick disconnect couplings of the HK series are single shut-off, double shut-off or straight-through. The double shut-off version is to be earmarked for hazardous media such as acids, alkalis, hot water or steam. Single shut-off couplings can be equipped with a non-return valve in the socket or nipple, depending on the application.
During connecting the valves do not push against each other until the coupling is shut off to the outside. Conversely, they are only separated when the valves are closed. This type of quick disconnect coupling works splash-free.
ST Series
-
Straight-through hydraulic and pharmaceutical coupling
The ST coupling series is characterized by its extremely robust design. It is particularly eligible for applications where the flow must be guaranteed even with highly viscous media such as greases and a shut-off can be dispensed with.
