The manufacturer, Witte, is based in Tornesch, Germany, with offices in the United States and China. Witte is a specialized manufacturer of gear pumps and associated spare parts and services for the chemical, plastic and polymer processing, food and beverage, and pharmaceutical industries. 

DOPAG has added two progressive cavity pump systems for 1K and 2K materials to its product range: rotordis for processing single-component materials, and rotormix for metering and mixing multi-component materials. 

A progressive cavity (PC) pump is a positive displacement pump that facilitates accurate feeding of medium- to high-viscosity materials such as thermal pastes or gels. It ensures minimal waste of material, reducing the environmental impact of the manufacturing process. PC pumps also provide many operational advantages, including continuous flow (doesn’t require reload), constant volume at variable speeds, no pulsation, and low maintenance. 

Careful consideration must be taken with pump selection when handling the transfer of glues. Depending on the type, these adhesives can be highly viscous and often harden and solidify when exposed to air. Glues are typically either water or solvent based; in this instance, the former is relevant.

While many filling technologies exist, gravimetric or net weight fillers remain a predominant fill method in the CASE industry. These fillers utilize a scale to measure the precise amount of product dispensed to a container.

Burt Process Equipment recently announced it will offer a free “Piston Pump & Pumping Systems” training.
