“The mobile pump educational center has been completely renovated for 2010,” states Rick White, OTP Pump Specialist. “The 1,200-square-foot vehicle includes operational interactive pump displays, and a theater for viewing pump training videos.”

Each tour stop offers trade professionals valuable opportunities to gain hands-on training from Grundfos Pumps and OTP associates and the ability to experience interactive pump displays.   Features include

• The award-winning, Multi-Stage CR-H, the perfect solution for ANSI pump users seeking improved efficiency and increased longevity for their existing pumps.
• The new ALPHA™, an energy-optimized, 115-volt circulator featuring a permanent magnet motor design that will cut power consumption by a minimum of 50%.
• Thinking Buildings Universe (ThinkingBuildings.com), a new online resource offering contractors and engineers a complete range of information and tools on pumps to help make their building projects come together more smoothly.

“We are stocking nearly every standard seal configuration possible to service the Durco Group I and Group II pumps,” states Tim Davis, Pump Specialist. “We have both 1-3/8” and 1-7/8” shaft sizes to support both large bore and standard bore stuffing boxes.”

The Flowserve ISC2 Series is a complete family of mechanical seals that provide exceptional reliability and standardization over a wide variety of industrial applications. It is the preferred mechanical seal for ANSI and general service pump applications and the seal design is so versatile it may be the only seal required by some facilities.  Facilities that standardize on the ISC2 will benefit from less inventory, greater flexibility, rapid availability, less downtime, and longer seal life.

The ISC2 mechanical seal introduces new technology exclusive to Flowserve and offers many upgrades to competitive seals.

• Exclusive Thermal Management Technology – tolerates dry running and cavitation events associated with “bad actors”.  The addition of carbon graphite between the rotary face and metal components acts as a heat sink to lower seal face generated heat.
• Square Head Pin - centered in the rotary face the square head self-aligns to evenly distribute torque loads, thus reducing face fractures.  The torque carrying capability is three times that of similar competitive seals.
• Throttle Bushing – increased size of the throttle or “disaster bushing”.  When seal failures do occur, the process can be directed to the drain port for added safety, and to provide an improved housekeeping advantage.
• Enhanced Barrier Circulation – groove machined in the gland to assist with barrier fluid circulation.  The added circulation further helps to keep the seal faces clean and operating cooler.
• Thicker Bellows - manufactured bellows thickest in the industry. Available in sizes up to 3.750″.
• Improved Set Screw Material – made from 17-4 H900 stainless steel to insure a positive bite into the sleeve/shaft, thus reducing slippage and galling of the drive collar.  This upgrade also makes it easier to remove the seal if required.

ISC2 seals meet all major international standards and ISC2-682 seals help customers align their standardization programs with the sealing industry’s most comprehensive best-practice standard: API 682/ISO 21049.

GIW and OTP will feature the new ZW series double suction vertical pump, which is used for abrasive slurries, dewatering, floor cleanup and process transfer. The ZW pump model includes a vertical cantilever design to help eliminate unnecessary downtime and its semi-open impeller design allows large solids to pass freely through the ZW pump.

GIW and OTP will also exhibit the corrosion-resistant, abrasion-resistant, high-performance LCC-R slurry pumps which are designed for solids-laden waste water and aggressive slurries. Using proven advanced hydraulics for metal pumps, GIW engineers have transferred this efficiency into a new rubber-lined impeller design for the LCC-R.

Look for GIW and OTP Nitro at booth #1430 at Coal Prep 2010 beginning April 27, 2010.

An automotive components plant was having trouble with a horizontal base mounted pump in its machining process.  This pump was used to circulate 176 degree Fahrenheit quench oil through a filter and back to a collection tank.  The hot oil with suspended metal fines caused frequent mechanical seal failures which resulted in regular oil leakage.  After some time, the performance got so bad that the customer actually remounted the pump inside a basin to collect the ongoing oil leakage.

When the customer first contacted us, we considered replacing the pump with a Gusher vertical immersion pump, which we have often used successfully in similar applications.  However, there was not enough room inside the tank to mount the pump.

After reviewing the application further, we installed a Gusher 7550 EC series vertical pump .  We selected this pump because its enclosed column allows it to be mounted outside the tank and it was not fitted with a mechanical seal.  Its jacketed ball bearing housing is ideal for high temperature applications.  Although this pump initially cost three times more than the pump it replaced, it quickly provided maintenance cost savings by eliminating seal failures and the resulting mess of a leaking pump.

We installed the first Gusher pump over three years ago and it is still running with no problems.  The  customer has since purchased two more pumps for similar service in other areas of the plant and is now looking into making this pump a standard at their other manufacturings plants.

Gusher Pump proved again to be a good partner with just the right pump to solve any application.

OTP news and events

Coal slurry pumps are essential part of the mineral processing in a coal prep plant.   A common problem in these plants is keeping the impeller properly adjusted as the parts wear.  Improper impeller adjustment results in premature wear to the liquid end of the pump, and can affect the efficiency and performance of the entire system.

However, impeller adjustment can be a dreaded job for a mechanic.  The atmospheric corrosion present in most prep plants often causes the bearing assemblies to seize to the pedestal, and the adjusting mechanisms to become inoperable.

Recently a customer voiced his concerns about this problem. We listened and presented the customer with a customized solution.

The customer agreed and purchased a new pedestal that was sent directly to our Middletown Ohio pump repair facility. We machined the pedestal to accept new removable 316ss seats, while maintaining tolerances. (The stainless seats will not seize to the cast iron bearing housing).  We then manufactured and installed a new design adjuster mechanism to allow the mechanic to adjust the impeller from the rear of the pump – making adjusting faster, easier and safer.

The coal prep customer is pleased and OTP is in the process of upgrading other plants’ slurry pumps as well.
