The benefits of Gather pumps are reflected in the increase in sales of Gather pumps and systems over the last 3 years. Here are the benefits customers are putting to use for their production.
1. Magnet coupling – hermetically sealed
2. Pulsation-free delivery & dosing – modular system for a large operating range
3. Use of non-lubricating liquids – GATHER material expertise
4. Cooling magnetic system & slide bearings by internal circulation
5. Robust design and long service life
6. Low-noise operation
Due to its construction type, the pumps are characterized by low-noise operation. The noise development is almost limited to motor noise.
The magnetic coupling ensures contactless torque transmission from the drive to the pump shaft. Unlike mechanical seals, it is not subject to wear and tear and is absolutely maintenance-free. It is hermetically sealed and there is no leakage of the pumped medium. This is a decisive factor, especially with concentrated, aggressive media and those that are hazardous to health. In addition, it allows easy pump head replacement.
Due to the operation of the turbine pump, a pulsation-free, flexibly adjustable flow rate can be attained. The speed-dependent delivery characteristic enables a wide flow rate range with differential pressures up to 5 bar. With four geometric variants, flow rates can be attained within operating ranges between 20 and 3600 liters per hour.
Operation with non-lubrication liquids is made possible, amongst other things, by using chemically resistant and high-precision manufactured materials. The pump body and shafts are made of stainless steel, Hastelloy® or titanium, and the slide bearings e.g. of carbon or plastic. The range of viscosities is between ν = 0,3 mm2/s to 100 mm2/s.
Internal flushing channels and holes convey a small part of the flow from the delivery side through the slide bearings and back to the suction side. This leads to internal cooling of the magnetic system and the slide bearings. In addition, the necessary sliding film is created on the slide bearings which ensures durable functionality.
The use of a magnetic coupling, internal cooling system, the pump design, and the high precision of the components result in a very robust pump with an extremely long service life. Depending on the application (medium) the pumps operate maintenance-free.
