Magnetic coupling

The CHEM gear pump series was developed especially for the requirements of the chemical industry. The series is used for pumping and transferring low to medium viscosity media. The CHEM series is extremely flexible in its design and areas of application. Technical details: — Suction pressures from vacuum up to 15 bar and suction pressures with magnetic coupling up to 25 bar — Delivery volume 1.28 cc/rev to 12,000 cc/rev — Temperatures up to 300 degrees — As special pumps for the chemical industry according to customer specifications — Viscosities up to 1.000.000 mPas

Chemical pump with electrical temperature control. The CHEM series is designed to be easy to maintain. Separate pump covers allow a quick inspection of the inner workings from both sides of the pump. To adjust the axial clearance we use shims which can be varied according to process parameters. Chemical pumps of the CHEM series are offered as standard versions with components made of stainless steel or as special versions with coated or ceramic materials. To bring or maintain the pump at process temperature, two temperature control variants can be used, electric and hydraulic.

Stainless steel metering gear pump for the delivery of chemical raw materials for the production of pharmaceutical products. CHEM metering pumps are also used to pump isocyanate, sulphuric acid, polyol or essential oils. With the appropriate combination of materials, many critical applications can be realized and a variety of low-viscosity fluids can be pumped. The range of applications extends from classic transfer and metering tasks in the chemical and pharmaceutical industry to the pumping of monomers, oligomers and prepolymers in polymer production. These chemical pumps are suitable for even the most difficult tasks and impress with their reliability and dosing accuracy in both vacuum and high-pressure applications. Typical applications for this pump type are in the chemical, cosmetics, food, petrochemical and polymer industries

Witte chemical pumps are used as dosing pumps for a variety of fluids. Pumps of the CHEM series are designed and assembled exclusively at the Tornesch site, thus guaranteeing highest reliability and quality. For all our series we offer a comprehensive spare parts service on request. In addition, we also install the pumps directly at our customer's plant. Dosing pumps of the CHEM series are extremely flexible in their design and can be offered in various variants and equipment thanks to a modular system. Differential pressures up to 120 bar, suction pressures vacuum up to 15 bar Temperatures up to max 500 °C in combination with a magnetic coupling. Viscosities up to 1.000.000 mPas or higher Components made of stainless steel, ceramic and special materials Flow rates from 20 l/h to 170,000 l/h
