The latest pumps and valves offer reliability and hygienic performance
Positive displacement pump
Ampco Pumps enhanced the traditional design of its ZP1-style pump with the patent-pending ZP1+ positive displacement pump. This advanced design changes the position of the dynamic O-ring for better performance and faster maintenance, the company said. Seal maintenance times are cut in half using ZP1+ technology. ZP1+ dynamic O-rings can be changed without removing the body or disconnecting the pump from the piping system, providing simple maintenance and increased production times. The one-piece sleeve design seals the pump if the rotors are removed for clean-in-place processing.
Hygienic high-pressure pump
The Triplex G3F process diaphragm pump from LEWA GmbH has an aseptic design with a collecting pipe and pressure transmitter solution. The pump stands out for its hermetically sealed diaphragm pump heads, its high-power drive unit and its low-noise emissions. The hermetically sealed diaphragm pump does not require plunger flushing, substantially lowering the risk of the system’s re-contaminating the end product.

Heavy-duty rotary valves
Coperion K-Tron started U.S. production of Coperion Germany type ZRD rotary valves in Salina, Kan. The Coperion brand rotary valves are being added to the full line of Aerolock rotary valves. They are specially designed for food applications. The valves are engineered for heavy-duty industrial service with pressure differentials up to 21 pounds per square inch gauge (PSIG) and temperatures up to 212 degrees Fahrenheit; higher temperature options are available. They are often used as discharging and metering valves for conveying products in powder and granular form.
Flowmeter for high-hygienic applications
Using the patented surface acoustic wave technology, Burkert Fluid Control Systems’ new FLOWave flowmeters need no sensor elements in the measuring tube and provide reliable results even in challenging hygienic applications. Specific processes are controlled based on flow-rate measurements for the production of food and beverages in all clean utilities applications. The devices meet the highest hygiene standards and are durable and resistant to disruptive influences such as vibrations and magnetic fields. The lightweight energy-saving devices can be operated in any installation situation and aid in the qualification and validation of production, cleaning and sterilization processes, the company said. FLOWave offers a range of advantages, including flexibility, cleanability, a compact size, a lightweight design and easy installation and handling.
Rotary lobe pump for viscous media
GEA expanded its Novalobe pump range with the large-volume GEA Hilge Novalobe 60. The robust rotary lobe pump is specifically designed for pumping and dosing highly viscous media with large particles. This new development meets the hygiene standards of the European Hygienic Engineering & Design Group guidelines for applications in the food, pharmaceutical and chemical industries. The lobe pump is part of the GEA Varipump line, which stands for versatility and flexibility.
Minidisc regulating and control valves
Lumaco offers the Minidisc regulating and control valve series for food, dairy and beverage applications. The valves are ideal for applications and processes that demand regulating and controlling product flow while meeting the requirements of 3-A Sanitary Standards. The Minidisc valve, equipped with a digital electro pneumatic positioner, optimizes product flow and maximizes efficiency. Processors can control and monitor valve performance from the built-in graphic display and/or from the control room when the valve is connected via a fieldbus interface.
Steam and water mixing valve
Archon said its steam and water mixing valve unit, model WD2010, has a simple design and is easy to use. With few moving parts and a wide range of operating capabilities, the unit is capable of handling 200 PSIG of steam. Steam and cold water are carefully and thoroughly mixed to provide “instant” hot water on demand. Using the proportional flow water and steam control valves, the operator can adjust the washdown station to deliver the desired hot water temperature, as indicated on the dial thermometer located in the mixed water discharge. By depressing the ergonomically designed fail-safe trigger of the hand-held spray nozzle or the optional spray lance, the operator can direct a steady flow of hot water from a fine spray to a solid jet.
4-inch Y-ball check valve
Sanitary Solutions Inc. said it is making the industry’s first and only 4-inch Y-ball check valve. Y-ball check valves are primarily found in the beverage, dairy, chemical and tank industries, where product flow applications require the prevention of reverse flow. The addition of a 4-inch model allows customers to utilize the full 4-inch port to increase flow. This will, in turn, increase product volume per day, therefore increasing daily revenue for the user, the company said. The sanitary stainless-steel valve is polished to meet a 3-A sanitary finish.
Positive displacement pumps
SPX Flow’s new Waukesha Cherry-Burrell Universal 3 (U3) series positive displacement pump provides a long life and hygienic performance for dairy, food and beverage applications. The pump series incorporates a front-loading seal and offers a high level of robustness to further extend life time and reliability, the company said. Improved seal life and greater torque capacity are created with shorter larger-diameter shafts. This increases reliability of the units and enables their use in higher-pressure applications. As with other Universal pump ranges, the U3 series has close running clearance rotors to further enhance longevity.
Round vacuum pump
Piab’s new round vacuum pump is easy to mount and install directly into a vacuum line. The round pump is based on Midi Coax cartridge technology, which provides a large amount of vacuum flow with minimal air consumption. Midi Coax is an ejector technology based on a multi-stage concept for creating vacuum with compressed air. By integrating the internal components of a multi-stage vacuum pump into a vacuum cartridge, Midi Coax allows for a smaller, more efficient, more reliable and highly flexible technology. With its cylindrical shape, the round pump fits well in cramped areas. The company said energy efficiency is gained by using Coax cartridges. The vacuum and exhaust are in line, making it easy to install into existing hose or pipe lines. Made from polyphenylene sulfide, the round pump can withstand a variety of environments.
Twin-screw pump for large particles
Fristam expanded its twin-screw pump lineup with the release of the FDS 4 pump. The FDS 4 provides high flow rates and the ability to pump larger particles. The pump provides displacements up to 90.682 cubic inches per revolution — more than twice as much as the next largest model, according to the company. It is ideal for the transfer of cheese curd, mozzarella, cottage cheese and cream cheese, as well as cheese inclusions such as fruit and vegetable chunks or nuts into cream cheese. The FDS 4 also handles entrained air applications such as whipped cream cheese without becoming air-bound. The FDS 4 is designed to be easy to operate and maintain.
