Chemical dosing pumps - Import export

Stainless steel gear pump for the delivery of alcohols, isocyanates or gels. The exact volumetric dosing of this series guarantees a low-pulsation and constant flow rate. Due to its compact size and high precision, the CHEM MINI is ideally suited for use in laboratories. Parts in contact with the medium can be made of stainless steel or ceramic materials. The series is available in sizes from 0.2-9-5.5 to 2.95-14-28, other sizes are also available on request. The range of application covers classic transfer and dosing tasks in the chemical and pharmaceutical industry. Due to decades of design experience and optimum material selection, this pump type is suitable for even the most difficult tasks and convinces by its reliability and dosing accuracy in vacuum applications.

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

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.

Chemical pumps of the CHEM series are used as a modified version as submersible pumps for emptying drums and containers. For example, chemicals such as liquid sulphur are pumped at temperatures up to 150 °C. The series is well suited to transfer low-viscosity media at relatively high pressures. — For viscosities up to 1.000.000 mPas — Temperatures up to 500 °C as special version — Differential pressures up to 120 bar — Suction pressures from vacuum to 15 bar Submersible suspension pumps are designed in such a way that the pumps are submerged in the container with the medium and the medium is sucked in via the flangeless suction side. The medium then enters the process from the tank via a pipe from the discharge side. Submersible suspension pumps are often made of special or stainless steels. A special feature of these pumps, as a rule no additional seals are required on the pump. Only the tank is sealed towards the atmosphere.

We bring our success, our wealth of experience and our know-how to the chemical industry. The requirement to pump viscous and sticky substances out of a vacuum is no easy task. However, our CHEM design easily meets this requirement. The requirements for dosing and transfer pumps as well as for distillate pumps in the CBD segment, for example, also match our CHEM design so that you get a pump solution for your entire distillation process with just one pump. More than 600 pumps of this design are running reliably in a wide range of cannabis applications at a number of our US customers. This robust and reliable pump series is used worldwide in demanding processes in the chemical and pharmaceutical industries.
