Goulds CW Pumps for Abrasive Slurries

Product Description

Single -Stage, Enclosed-Impeller, Back Pull Out Process Pumps for Abrasive Slurries.  The model CW/CWX horizontal pumps are designed to efficiently pump liquids with abrasive solids in suspension.  With wear parts made of HC600 chrome iron, the CW/CWX pumps give long life and superior performance in all types of slurry applications.  The model CWX with Shearpeller has air and solids - handling capabilities significantly superior to conventional design.

Specifications

  • Capacities to 10000 GPM (2273 m3/h)
  • Heads to 300 feet (91 m)
  • Pressures to 175 PSIG (1206 kPa)
  • Solids to 5 inches (127 mm) 
Design Features
  • Maximum interchangeability of parts reduces spare parts inventory.
  • Back pull-out design for easy maintenance on bearings, seals, packing impeller and wear plate- without disturbing the piping or driver.
  • Replaceable, wear resistant shaft sleeve protects the steel shaft for the length of the stuffing box and extends through the packing gland.
  • Optional EquisealTM Dynamic Seal on the CW models eliminates shaft seal and packing maintenance as well as gland water requirement.
  • Enclosed Impeller - abrasion resistant hard metal enclosed impellers have low velocities and are accurately cast for years of trouble-free service.
  • External Impeller Adjustment on the CW model maintains efficiency, simple and fast.
  • Chrome Iron Construction for maximum abrasion and corrosion resistance.  

Model Features

Packed Stuffing Box
Style C-011 Packing is the standard stuffing box arrangement supplied with the CW pump. The stuffing box contains a packing base ring, a minimum of four rings of packing, a seal cage centered in the box, and a split packing gland. The stuffing box inlet tap is located directly over the seal cage. An out connection is provided at the bottom of the box which may be used to flush solids from the box, or used as a test connection.
Sealing Flexibility
Style C-022 Dynamic Seal is the optional stuffing box arrangement used to effectively control dilution, and minimize sealing water requirements. A maximum of one-half gallon per minute of clear water is all that is required for sealing with this arrangement, 1/4 gpm is normal. The Dynamic Seal used in a centrifugal pump replaces the conventional shaft seal, and is suitable for handling most concentrations of slurries. It may be used on any application where a positive static suction head exists. 
 
The Dynamic Seal embodies a special open expeller with vanes on the outer face rotating in a circular chamber with stationary vanes on the inner chamber wall. A pipe connection is provided to admit liquid to the dynamic seal for flushing, cooling, and ensuring steady operation. If the solid content of the pumped product is low, it can be circulated through the seal. With heavy slurries, a small amount of clear or clarified water may be required to prevent a product build up in the seal area. A disc type auxiliary static seal, that comes into operation only when the pump is not running, is located behind the dynamic seal.
