The lube oil system for a gas turbine is one of the most important systems in the turbine operation. The oil quality is critical to the life and functionality of the bearings and auxiliary drives. Gas turbine lube oil serves tow functions: lubrication and removal of heat from the bearings. The primary contaminants that are found in mineral base oils used with gas turbines are fine particulate and trace amounts of water. Typically, water in the oil is an uncommon probelm except for the effect of condensation. Kaydon designed the KP30 system to meet the cleanliness requirements of today's gas turbine lube oil. If the oil is not properly maintained, an untimely failure due to contaminated oil may possibly result in a forced plant outage. In fact, a 10-year study conducted by the North American Electric Reliability Council (NERC) recognized turbine bearing and lube system component failures as the leading cause offorced outages for gas turbines.

Description

The KP30 gpm removes solid contamination via a 2.8 micron absolute (BETA=75) dual phase particulate filter cartridge per ANSI(NFPA) T3.10.8.8RI Multipass test, and removes water with the new Kaydon "Quick-Dry" Element.

Features
  • Removal of particulate smaller than bearing and valve clearances with ANSI(NFPA) 3 micron absolute rated filter elements (KM6036-05)
  • Kaydon "Quick-Dry" water removal filter (KQD6036-5)
  • Optional Heater
  • Ideal for phosphate ester oils - no brass or copper
  • Viton Seals
  • Optional portability kit that includes casters, hoses and extension cord.
Benefits
  • Longer Oil Life
  • Reduced Oil-Related Equipment Failures
  • Fewer Shutdowns
  • Reduced Sludge and Pipe Scale Formation
  • Reduction of Total Acid Number (TAN)
  • Less Costly Rebuilds


  • The KP30 is compact and conveniently skid mounted for ease of installation. In addition, the skid incorporates provisions for lifting the unit by fork lift. Four 0.88" holes are provided for permanent mounting. In the event that it is necessary to disassemble the KP30 in order to fit in it is necessary to disassemble the KP30 in order to fit in a tight space,it is easily disassembled. Most of the components are bolted to the skid. The skid dimensions are H = 53" W = 48" D = 35". Dry weight = 250 lb.
  • Inlet connection - 2" NPT with ball valve for isolation. Large inlet to accommodate turbine lube oil at reduced temperatures.

  • Suction Strainer - 2" cleanable 30 mesh "Y" type strainer to protect the pump.
  • Pump & Motor - 30 gpm gear pump with internal relief valve set at 90 psid. The pump is driven by a 5 hp 460 VAC TEFC electric motor.
  • Pump & Motor - 30 gpm gear pump with internal relief valve set at 90 psid. The pump is driven by a 5 hp 460 VAC TEFC electric motor.
  • Heater - (optional) The thermostatically regulated 5kW heater increases the temperature of the oil five(5) degrees per pass with a watt density of 16. The heater is sized to raise the oil temperature quickly and to keep the oil flowing during periods of extreme cold.
  • Sample Port - The sample port is equipped with a ball valve and pig tail for ease in taking oil samples. Oil samples taken from this port indicate the oil cleanliness in the lube oil reservoir.
  • Differential Pressure Gauges - Pressure gauges are mounted on the filter vessel to indicate when the element needs changing. It is necessary to replace the filter element when the differential pressure reaches 25 psid.
  • Control Panel - NEMA 4 rated control panel that contains the on/off switch and 460 VAC. 3-phase, 60 Hz electric connection.
  • Filter#2 - The second filter vessel is a duplicate of the first and uses the Kaydon "Quick-Dry" water removal element.
  • Outlet Connection - 1.5" NPT with ball valve for isolation.
  • Filter#1 - Particulate filter, equipped with one Kaydon 2.8 micron wire supported dual-phase microfiberglass BETA Absolute particulate removal element. This 6" x 36" filter element is designed for maximum dirt holding capacity with exceptional particulate removal efficiency. The element is protected by an internal bypass valve set at 40 psid. A convenient "Y" top handle is provided for filter element removal and installation. No toolsare required to remove the filter element. The filter vessel is equipped with an air vent and ball valve actuated 1/4" NPT oil drain port.
