Equipment Round Up February 2009 - Pumps and Fluid Handling
February's Equipment Round Up focuses on pumps and fluid handling products.
Reduce washdown costs
A patented control technology for high-pressure positive displacement process pumps, the Unigy pump-control system employs mathematical models to reduce energy consumption and maintenance costs for washdown applications in the food and beverage industry. Compatible with both clean-in-place and steam-in-place operations, this technology employs intelligent pump-control software to produce the precise flow rates and pressures demanded by the application. It continually senses demand and manages pump speed and applied torque to satisfy variations in process demand, significantly lowering energy consumption and costs normally associated with maintaining an overworked system. It can be retrofitted into existing process systems and incorporated into new installations.

Easy cleaning gate valves
For material handling applications that require daily cleaning or sanitation of equipment, Quick Clean Orifice Gate Valves can be readily disassembled, cleaned and reassembled without tools for fast, flexible maintenance. Traditional knife gates or butterfly valves rely on soft rubber seals that erode or tear away during use, allowing material leakage. This patented design eliminates those problems, improving production and decreasing labor and equipment costs. The blade and seal design allows the valve to “self-clean” on the opening stroke, preventing material from packing on the valve’s internal seals.

Thin liquid pumps
The innovative LVP Series of stainless steel vane pumps provides up to 14 bar (200 PSI) thin liquid capability at capacities up to 160 GPM. The pumps are designed for thin, corrosive liquids at higher pressures than other positive displacement pumps. These pumps provide exceptional performance, advanced durability and application flexibility. Their simple installation and ease of maintenance help realize enhanced productivity and a lower total cost of ownership. They’re also maintenance-friendly, allowing complete draining and easy vane or seal replacement without removing the pump from its system.

Many sizes and pressures
Series PZ pulse metering pumps are suitable for accurate, reliable injection of a variety of liquids including chemicals, nutrients and disinfectants. The pumps have powerful control options and a range of sizes and pressures (from 1 to 1,300 ml/min at pressures up to 220 psi). Flow rates and accuracy are unaffected by fluctuations in voltage; they will operate any single phase voltage from 94 VAC to 264 VAC. The pumps are available in manual control, external input and programmable models. All of the control features are onboard every programmable model pump, including pH control and residual chlorine control, without requiring a separate PID controller.

Durable and long-lasting
Durability is a key advantage of the Vax valve, which is suitable for applications that require fast actuation, durability and reliability. It combines a process valve and an actuator in a single integrated unit with only one moving part. Its coaxial design offers high flow rates with minimal pressure loss, while extending the valve’s cycle life by as much as 10 times that of conventional valves. The electric version functions like a direct acting solenoid valve. Since it works with the forces of flow instead of against them, it is suitable for most vacuum, gaseous, gelatinous, highly viscous, pasty, aggressive or contaminated or recycled fluids and gases from vacuum to 600 PSI.

High viscosity pumps
The newly redesigned Masterflex B/T Process Pumps enable bulk transfer of viscous and shear-sensitive fluids with ease, cost-effectiveness and reliability. At the core of this design is the pump head door that opens fully to allow easy access to change or inspect the tubing. Optimal occlusion is automatic when the door is closed and latched. A secure retention mechanism grips the tubing for trouble-free loading and prevents tubing creep or roll. Additionally, a new flush-mounted, corrosion-proof latch offers one-handed opening and closing without the use of tools. The consistent performance of these pumps relies on the pump tubing which features retention marks to indicate the exact tubing alignment needed for optimal performance and tubing life.Cole-Parmer; Vernon Hills, Ill.
Series 88 High Purity Tube Full Port 3 Piece Ball Valves are designed specifically for the demanding process requirements found in food and similar industries where aseptic conditions are required. They have 5 percent or less ferrite content to prevent rouging (less than 1 percent ferrite is available as an option). All welded end parts are made from 316L stainless steel supplied with very low sulphur content. All wetted parts are polished to 14-18 Ra, 240 grit.Sharpe Valves; Northlake, Ill.
