CPT-4 - Power Line Insulator Washing

Hot Line Insulator Washing - Hot Line Washing is basically a procedure where insulators on electrical lines are cleaned with water while the electricity is energized (on).  If the insulators are not cleaned, a flashover may occur causing brownouts, blackouts and damaged equipment. The Waterous CPT-4 pump is an ideal solution for hot line insulator washing. With pressures up to 800 PSI (55 bar), the insulators can be cleaned while power is still supplied to customers.

Specifications

  • Ni-resist; special “stepped” designed wear rings reduce internal leakage & increase efficiency
  • Bronze, hydraulically and mechanically balanced impellers
  • Impeller hubs are “stepped” to minimize internal bypass
  • High-tensile, close-grained gray iron (bronze/gunmetal optional), two-piece, horizontally-split volute body
  • Adjustable braided flexible graphite (BFG) packing
  • Available with either clockwise or counter-clockwise rotation of input shaft
  • T Series Transmission consists of a close-grained, gray iron casing with constant-mesh, stainless steel helical gears

Options and Accessories

  • Priming System: An electric, oil-free rotary vane primer mounted directly on a Waterous split-shaft pump transmission or separately mounted combined with a Waterous priming valve forms the priming system. A lubrication option allows the use of Prime-Safe lubricant (priming tank is required when the lubrication option is selected).
  • Pressure Control System: The Waterous Intake Relief Valve system is designed to act as a safety valve by "dumping" excess pressure from the inlet side of the pump. The Discharge Relief Valve provides sensitive pump control to protect firefighters from sudden pressure surges resulting from changes in discharge flows from the pump.
  • Manifold Drain Valve: Drains all points of the pump simultaneously with the operation of a single control.
  • Corrosion Protection: Replaceable zinc element that is installed directly on the pump intake piping and into the pump waterway. These anodes sacrifice the zinc element to galvanic corrosion.
  • Discharge Valves: Your choice of the trusted Waterous 1/4 turn 2.5 inch and 3.5 inch ball-type discharge valve. Both options come standard with chrome-plated brass ball and hydraulically balanced seal assembly.
  • Overheat Protection Manager: The OPM consists of an illuminated warning light on the operator's panel whenever the pump approaches an overheat condition. Optional audible alarm is available.
  • Tachometer: Tachometer drive standard and operates at 1/2 input shaft speed.
