Alfa Laval Gains PMO Compliance for Mix Proof ValvesPleasant Prairie, Wis.-A "Memoranda of Milk Ordinance Equipment Compliance" ("M-b Letter") was issued by the U.S. FDA Center for Food Safety and Applied Nutrition-Milk Safety Branch, advising Regional Milk Specialists that the Unique PMO Sanitary Mixproof Valve meets the applicable provisions of the Grade 'A' Pasteurized Milk Ordinance (PMO) when used to separate cleaning product solution and milk and milk products. The memorandum further detailed required construction, installation, and operational requirements for the valve that must be maintained to ensure compliance.
Alfa LavalThe Unique PMO Mixproof Valve is designed for automated dairy operations requiring double-block-and-bleed functionality. It eliminates the need for manual pipe swing connections and/or multiple seat valves, while offering optimum hygiene without o-rings or sliding steel parts. Dome-free upper and lower bodies allow for complete drainage.
The Unique PMO is available in sizes 2", 2.5", 3", and 4". Valves are equipped with the ThinkTop® control and indication unit, providing a flexible control interface with your automation system.
Alfa Laval has launched the Solid C Series centrifugal pumps, a new series of centrifugal pumps for standard sanitary duties. As the next generation of Tri-Clover brand pumps, Solid C pumps improve on the technology of the C Series, which has been an industry standard for 35 years. This new design offers an improved seal, lower NPSHr and better performance for standard duties in the beverage, food, personal care, dairy and pharmaceutical industries. The Solid C is a cost-effective standard duty pump intended for use in non-critical, less demanding applications. All product-wetted parts are in AISI 316L stainless steel. It is a high-value standard pump which exceeds hygiene standards and complies with 3A and CE and has EHEDG certification.
The pump range consists of four pumps with the following performance data:
• inlet pressure: 50 psi
• capacity: 400 gpm
• head: 400 ft
• temperature: up to 250°F
All Solid C pump sizes have the high-quality shaft seal used in Alfa Laval's 14 models of LKH premium pumps. Using the same shaft seal in both pumps simplifies the number of spare parts needed in stock. Conversion kits are available to change from a single to a single flushed seal.
The shaft seal can be removed by hand from the front of the pump without removing the backplate. This means that the shaft seal and O-rings can be changed in minutes. In addition, the compression coupling on the shaft is self-centering. The pump casing can be fitted by a single person, without assistance.
Solid C pumps are supplied with a three-year warranty on all non-wear parts if genuine spare parts have been used.
Sudmo North AmericaThe first-ever Cheese Curd Outlet PMO Mix Proof Valve specifically designed to automate the cheese curd vat transfer process was introduced by Sudmo North America. The company now offers a PMO mix proof valve that can pass particulates up to 1 1/2" in size without plugging the valve. This revolutionary new valve greatly simplifies the valving and piping of cheese vat applications and eliminates the cleaning problems associated with block and bleed systems. Sudmo PMO mix proof valves offer many proven advantages including leak-free changeover, a one-piece machined body, maintenance-free actuator, balanced stem, and the latest control technology. There are no special tools required for replacing seals.

Viking PumpViking Pump has expanded its gear reducer product line to include a new series of in-line gear reducers compatible with any positive displacement pump or other equipment needing speed reduction. The new gear reducers have the input and output shaft on the same centerline for easy alignment and maximum space savings.
All gear reducers in the new series offer double reduction, high efficiency and low noise levels. The gear reducers are available in ten different sizes, with ratios varying from 2.6:1 to 35.1:1. Available horsepower ranges from 0.5 to 350 hp (0.37 to 261 kW), while output speeds range from 50 to 673 rpm (with 1,750 rpm input).
The gear reducers offer universal mounting with either a solid input shaft, or a hollow input shaft combined with a NEMA C or IEC flange to close-couple to the motor. The direct mounting eliminates alignment problems as well as the need for a coupling set and a coupling guard between the motor and the reducer.
Viking is also introducing a Low Flow, High Hygiene Pump. The AccuLobe is the smallest member of Viking Pump's extensive lineup of rotary lobe pumps. Designed for metering, filling and transfer applications, its unique 5-lobe rotors and small 20 ml/rev displacement combines accurate dosing with minimal pulsation. Capacities to 9.2 gpm (32 lpm) and pressures to 220 psi (15 bar) are possible on fluids from 0 to 150,000 cSt viscosity.
The AccuLobe's sanitary/hygienic design is suitable for lab, pilot plant and production applications in food, beverage, biotech and pharmaceutical markets. It is 3A-conforming and has been tested and certified according to the EHEDG method for in-place cleanability of food processing equipment. It's low-shear, high viscosity capabilities also make it perfect for process ultrafiltration, creams and lotions, resins and coatings, inks and water treatment polymers. Front-loading seals allow fast and efficient maintenance.
APVAPV pumps and valves are among the most hygienic and advanced in the world. Designed and built around the customer's need for hygienic processing, product protection, and fast, easy maintenance. APV pumps and valves are backed by a 100-year track record for technological advances, process knowledge and dependability.
The centrifugal pump line manufactured by APV meets 3-A, FDA, USDA, BISSC and more. Major lines include the W+ Series, the most advance, high performance and sanitary pump for the demands of high quality products; and the V2, APV's economical solution to a wide range of pumping needs. APV's broad range of pumps also includes positive displacement pumps such as the DW and R Series.
The DW rotary lobe is ultra hygienic and so fast that it can often be both the product and CIP pump. APV's R Series pump line meets 3-A COP requirements and are known for easy disassembly and clean up equaling low maintenance costs. APV's wide range of valves includes a hygienic 3-A single seat design,a cutting-edge control unit,and an ultra-hygienic mix-proof valve designed to leave no surface unclean.
Versa-MaticVersa-Matic has released its Ultra-Matic 2" high efficiency pump. A completely redesigned air section provides increased pump performance while requiring less compressed air to operate. With a pumping capacity of up to 200 gallons per minute, the Ultra-Matic provides a performance increase of up to 30% compared to other air-operated double diaphragm (AODD) pumps.
The Ultra-Matic's performance increase can be attributed to enhanced volumetric efficiency and the ability for compressed air to completely evacuate the pump. The redesigned air section efficiently utilizes space and eliminates friction by way of a patented sliding exhaust valve that enables air to exit directly into the atmosphere. Air flows smoothly through the valve and center section, entering through one port and exiting through another. This design results in streamlined efficiency that saves costly compressed air.
In addition, the Ultra-Matic has fewer moving parts, minimizing repair and maintenance-while a positive pressure shifting mechanism eliminates stalling. Available for Versa-Matic's 2" AODD pumps, this industry-changing breakthrough is available in a variety of materials and styles, including plastic, aluminum, cast iron, and stainless steel. The Ultra-Matic is interchangeable with all existing bolted and clamped Versa-Matic pumps, and is retrofittable with Wilden 2" clamped-style pumps. Versa-Matic Pump Company, a unit of IDEX Corporation, is a recognized leader in the design and manufacture of air-operated double diaphragm pumps and accessories.
