Products & services
RotoTwin
Pathogens don't stand a chance! To meet the stringent requirements of the foodstuffs, pharmaceuticals, cosmetics or chemicals industry, companies working in this sector need equipment such as the RotoTwin® screw pump, which was designed to meet the strict EHEDG hygiene requirements. Two intermeshing rotating feed screws reliably deliver products with high to low viscosity as well as gaseous or volatile products. Due to the axial movement and low acceleration, the RotoTwin® never fails to impress with its powerful suction capability and gentle product delivery. The contactless operation of the feed screws makes the pump safe even when running dry. Even larger air bubbles in the pipe will not harm the pump. The pump’s ability to reverse the direction of rotation enables the medium to be pumped in both directions, making it possible to use the pump for filling or emptying
Progressing cavity pump
The progressing cavity pumps are exceptonally well suited for the conveyance of self-flowing liquids; from lower to high viscoity liquids, along with solid-laden solutions. The low pulsation and low shear contribute to the pumps ability convey highly abrasive, sticky or lumpy media as well as alkali and chemical medium with a dry stubstrat content rate of 45%. These are various designs and materials offered for the rotor, stator and the pumps case, even the drive. In this way, the best possible adaptution to customer requirement (pumped medium space, pressure etc.) can be guaranteed. In addition to reliable delivery, the progressive cavity pump is ideal for numerous dosing tasks. Reliable progressing cavity pumps are typically used in the following sectors: - Waste water - Biogas - Paper industry - Chemical industry - Food production - Pharmaceutical industry
Rotary lobe pump
Flexibility and efficiency. Rotary lobe pumps are robust and compact positive displacement pumps used in almost all industrial sectors. They pump a variety of media, including low-shear and low-pulsation materials, as well as abrasive, viscous, sticky, particle- and gas-laden materials. These pumps are particularly well-suited for pumping media ranging from thin to puncture-resistant. The pump can operate in both directions of rotation and can be easily equipped with various drive systems.
Compressed air diaphragm pump
Strong, safe, and dry. Diaphragm pumps are robust and dry-running safe. They are characterized by gentle pumping of products ranging from low-viscosity to high-viscosity and powdery materials. Their low-shear operation is particularly ideal for media with fragile or abrasive solids. Their ease of use and high operational reliability save time and resources. Compared to electric diaphragm pumps, pneumatic diaphragm pumps offer additional advantages. They can be used without a power supply and are very easy to operate in ATEX areas.
Peristaltic pump
Safe, even when it gets dry! Peristaltic pumps are versatile and completely safe to run dry. They effortlessly pump a wide range of media – from abrasive and particle-laden to gaseous substances. Thanks to their design with few moving parts, wear is minimal. This ensures the pumps' suction capacity is maintained throughout their entire service life. The closed system ensures maximum hygiene and reduces the risk of contamination. The hose can be quickly replaced if necessary, significantly reducing downtime and maintenance times.
Maintenance
We offer overhauls of pumps as well as sensitive industrial machinery and equipment. We perform overhauls and commissioning work either at our premises or in your factory in Switzerland or abroad.
Spare parts for pumps
The procurement, production, storage and supply of spare parts is a core competence of ROTOTEC AG. ln this respect, we work closely together with the respective manufacturers and industry partners. lt is our goal to be a reliable, flexible, multi-lingual, interesting, accommodating, innovative and long-term partner to our customers.

Kreiselpumpen
Efficient conveying technology. Centrifugal pumps are the preferred choice for constant-flow applications and are the most commonly used in industry. They impress with their robust design, high flow rate, and low maintenance requirements. Thanks to these properties, centrifugal pumps are particularly economical and versatile in numerous industries and sectors.
Screw pumps
Precise pumping. Screw pumps are suitable for pumping low- to high-viscosity, highly volatile, or gaseous media, even those with non-lubricating properties. The ability to simultaneously use the process pump for CIP or SIP cleaning makes this pump type particularly attractive for the food, pharmaceutical, and cosmetics industries. Contactless operation makes the pump safe to run dry and insensitive to gas content in the medium.
Ring piston pump
Tough on duty, gentle on the medium. Rotary piston pumps are reliable positive displacement pumps characterized by their versatile industrial applications. They pump low-viscosity to medium-viscosity media with low pulsation. Their special design guarantees low shear and good suction capacity of the pumped medium.
Agitators
Agitators that move. Agitators are indispensable in many industrial processes. They are used to mix, homogenize, or keep liquids or suspensions in motion. The choice of the right agitator depends on factors such as viscosity, container size, and the specific application. Fast-running agitators ensure thorough mixing, while slow-running agitators are used for low-shear processes.
Shredder
Proper shredding, trouble-free conveying. Shredders cut or tear cuttable particles such as textiles, food, or organic materials. At the same time, hard foreign matter is reliably separated. The result: significantly improved pumpability, fewer blockages, and effective protection of downstream plant equipment against clogging or damage. Depending on the requirements and desired degree of shredding, different technologies are used – such as single-shaft or twin-shaft shredders.
Separators
Individually adjust – flexibly separate. Our two-phase separators are specially designed for liquids with fibrous components – ideal for applications in industrial, agricultural, and biogas technology. Our separators enable energy-efficient, purely mechanical separation of solid and liquid components. The dry matter content can be continuously adjusted.
Mixing & blending
Mixing powders and liquids. The powder mixer is specifically designed for the reliable dissolving, emulsification, and homogenization of powdered and liquid components in liquids. The special pumping and mixing system produces a homogeneous, clump-free mixture in a single step. The powder mixer achieves a perfect, uniform, and hygienic product consistency. This is extremely powerful and economical. Our powder mixers are available as mobile, stationary, or as a simplified version with a powder feeder or powder dissolver.
Gear pump
Perfect metering, no pulsation Gear pumps are reversible positive displacement pumps capable of pumping low- to high-viscosity media without hard particles. They are characterized by their precise metering and reliability at low to high pressures. Furthermore, they are very compact, guarantee a non-pulsating flow rate, and are resistant to high temperatures. There are two main types: external and internal gear pumps.
