GIW joins OTP at Coal Prep 2010

NITRO WEST VIRGINIA – January 15, 2010 – GIW Industries and Ohio Transmission & Pump (OTP) will exhibit together at Coal Prep 2010. Coal Prep 2010 is the annual coal-processing exhibition taking place April 26-29, 2010 in Lexington, KY.

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.

Coal Prep Slurry Pumps Impeller Adjustment

OTP Industrial Solutions for Pump Applications
Written by Carl Gable

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.
