Best Practice ChemCore® ChemCore® series chemical pumps come as standard with stainlesssteel components, or there are special versions with coated or ceramic materials. The ChemCore® series was developed for easy maintenance. Separate pump covers make quick inspection of the interior possible from both sides of the pump. To adjust the axial clearance we use spacers that can be varied depending on the process parameters. Sealing technology: Eight different seal versions for different applications Stainless-steel housing as standard. Lots of special materials such as ceramic or coatings are possible....

Standard chemical pump CHEMICALS The ChemCore® gear pump series was specially developed for the requirements of the chemical industry. This series is used to pump and transfer low-to-medium viscous media and takes care of metering and transfer tasks. The versatile spectrum of use for these pumps ranges from organic and inorganic chemicals and foodgrade lubricants to polymers and pharmaceutical products. An extensive modular system provides optimal material pairings for corrosive or abrasive media. Technical designs Operating parameters Stainless steel · tantalum · titanium · Hastelloy® · ceramic...

Chemical pump for fine metering CHEMICALS The Mini series is based on the ChemCore® series and extends the range with pumps for extremely fine metering tasks. Amounts from 0.2 cm3/rev. to 2.95 cm3/rev. can be pumped. This pump type excels at maximum metering precision. The pumps are used for metering additives into extruders, among other applications. Technical designs Operating parameters Stainless steel · tantalum · titanium · Hastelloy® 1.4112 · and also all other processable ceramic and metal materials, such as 1.4571, Ferralium®, Ferro-Titanit®, Hastelloy®, etc. · optionally available with...

ChemCore® LZ: Drop-in-Replacement CHEMIKALIEN Replacement solution from WITTE for your Hermetic LZ gear pump WITTE now offers all users and operators of Hermetic-LZ gear pumps an alternative solution - our new ChemCore® LZ series. The LZ series, which was taken out of the Hermetic range in 2018, is still in operation in many plants. However, replacement pumps from the original manufacturer are no longer available. At WITTE you receive the complete pump including coupling connection with identical dimensions. This is a double advantage for our customers, because the system does not have to be...

Custom OEM solutions CHEMICALS WITTE offers modified chemical pumps for OEM customers. These pumps are usually specially tailored to the customer’s requirements. WITTE works with the customer to analyse the pumping task and draw up an initial solution. A pump is designed and prototype created depending on the required amount. The customer has ample oppor- tunity to test this prototype, and then the results are discussed and optimised together. The pumps can also be fitted with the customer’s name plate if desired and delivered quickly by order contract. Technical designs* Operating parameters*...

Metering systems/technology CHEMICALS Gear pumps are highly suitable for precise volumetric metering with high reproducibility. When used in combination with a mass flow meter and a control system, a self-regulating, absolutely precise pumping unit is created. A wide range of interfaces can be used to program the mass flow meter. Once defined, the mass flow meter instantly forwards even the smallest changes in flow to the connected drive unit and regulates the volumetric flow so that it always stays within the tolerance range. Sample structure of a metering system Mass flow meter: Mass flow meter...

WITTE Core Command® Pump control for your gear pump WITTE PUMPS & TECHNOLOGY GmbH is not only a manufacturer of gear pumps, but at the same time a system supplier offering complete solutions from a single source. The pump control WITTE Core Command® serves to expand your gear pump and can be easily integrated into your process. This type of control is specially adapted for use with WITTE gear pumps, but can also be used with pumps from other manufacturers. standards. The system is based on Siemens PLC S7-1200. Control to flow with external flow sensor Precise metering tasks can be realised with...
