Haight Expands Universal Design to Include Stainless Steel Models for the Ultimate in Gear Pump Simplicity, Flexibility and Adaptability

EVANSVILLE, WI, June 2, 2005 -- Haight Pumps has expanded their Universal Design PD Pump Series to include stainless steel models in 10, 15 and 20 gallon configurations.

Based On Success
Tried and proven in applications around the world, the Universal Series, with its adaptability and ease of maintainability has grown to become one of the most versatile, rotary gear positive displacement pumps on the market.

The result of ongoing R & D as well as extensive field-testing, the addition of stainless steel models gives end users a long lasting gear pump that can work with the most aggressive applications.

Patented Principles Make It Ideal For Problem Fluids
Using the Haight's pioneering (and patented) "gear within a gear" pumping principle, there are only two moving parts; a stainless steel outer gear and a plastic inner gear engineered to match the exact application. Hydraulic balancing ensures reliability and minimizes wear.

Its distinctive operating characteristics make it ideal for use with corrosive, high temperature, thin, corrosive and other aggressive problem fluids. Typical fluids include: phosphoric acid, caustic sodas, zylene, polymers, surfactants, flocculants, carbon black, isocyanates, sodium hydroxide, glycols, wastewater and other chemicals.

Customer Commitment As A Basis
The announcement, made by Gordon Durand, Division Manager of Haight Pumps, is part of the firms' plans to dramatically expand their family of PD pumps to include an even broader operating range as they focus on being a single source supplier.

According to Durand, "With over 65 years experience in the design, engineering and manufacturing of gear pumps, Haight remains on the cutting edge of pumping and process technology. Our people are continually looking for ways to provide solutions to end users problems, especially in the areas of poor lubricity, corrosives, abrasives and difficult to handle liquids. To that end, we continue to invest heavily in our R & D efforts and listen to customer needs in the process".

Durand continued, "Direct end user input was a key factor in the design of our new stainless series. When they asked for a stainless steel PD pump that had better specifications and features than similar models at competitive pricing, we listened. By carefully combining our proprietary designs with the best possible materials, we actually were able to build a better pump at a lower price. Moreover, using this formula as a basis, we plan to extend the scope and range of our stainless steel pumps even further",

Latest In Pumping Technology
Before the advent of this series, end users had to deal with galling, pump failures and unscheduled down-time. The Stainless Steel pumps in the Universal Series solve these problems with features not found in other gear pumps of this kind, including:
o No Galling - ensured by pump design and high hardness materials of construction
o Shaft Alignment - close coupling eliminates alignment and runout
o No Gearboxes - operate at standard motor speeds without the need for a gear reducer
o 316 L Stainless, low carbon steel - shaft, housing, pinion gear for better corrosion resistance and low lubricity
o Materials of Construction - for extended service life, reliability
o Reduced Pump Inventory Needs - one pump handles multiple service requirements
o Maintenance - easy service and inspection accessibility, simplified packing gland adjustments
o More - self priming, low shear, reversible flow, integral bolt-on relief valve

Other Features
Historically when a pump was ordered, it was application oriented towards a single pump configuration. With the advent of the Universal design, all pumps in the standard Haight product line are able to accept relief valves, lip seals, four types of mechanical seals or packing gland shaft seals. It is the only design on the market that allows end users to switch sealing methods on-line and in-place without the need for special tools.

Stainless Steel pump operating characteristics include: Capacities of 10, 15, 20 gpm; Lubricating fluids 250psid, non-lubricating fluids up to 100psid; temperature range from -40°F to 250°F; standard motor operating speeds of 900/1200/1800 rpm; inlet capacity of 20"Hg to 250 psi and a viscosity range from 32 SSU to 10,000 SSU.
