Ceramic materials - 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.

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.

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

These machines are capable of executing complex lapping routines while producing precise and repeatable results. These units, available for maximum component diameters of 51mm on the DL175, 114mm on the DL370, up to 170mm on the DL500, can lap a wide range of materials to very tight specifications. Excellent results have been obtained in the processing of a wide range of materials and components including glass, ceramics, crystals and ferrous materials. The Lapmaster line of Dual-Lap machines are based upon a two-way & three way planetary concept designed to yield very precise and repeatable results. Only the Inner and Outer Gears rotate allowing the carriers to move around the surface of the plates, whilst the top and bottom plate stay stationary. The larger DL500 and DL770 use a 3-way system, where the top plate, bottom plate and sun gear rotate.
