Series Description:Vikings 095C Series pumps are for rotating equipment lube oil filtration or cooling. They pump in one direction, regardless of which direction the shaft turns, to prevent backflushing a filter in the event the drive shaft is reversed. Typical applications include wind turbine gearbox lubrication, other large gearbox lube, and compressor and turbine lube.

Key Features and Benefits:● Catalog dimensions are provided as a baseline

only. The pump is designed to be easily adapted to fit different OEM application needs:

● Mounting flange and pilot can be machined to different dimensions so it will be slightly larger than the diameter of the drive gear, allowing easy shaft/gear insertion through a bulkhead.

● Pump mounting hole locations can be adjusted ● Pump shaft length and diameter can be adapted ● Ports can be tapped to SAE O-ring J1453, BSP

or NPT instead of flanged ● Other models available in which the suction port

is built into the mounting flange, to draw directly from the gearbox sump without a separate suction line.

● Pump has NO SHAFT SEAL. Shaft seals are the single greatest cause of pump downtime. Minimal lube oil leakage is allowed along the shaft back to the drive equipment, which also helps lubricate the thrust bearings.

● Two tapered roller bearings provide axial thrust control to positively locate the rotor, which ensures correct end clearance and prevents rotor contact with casing or head.

● A cylindrical roller bearing behind the rotor for radial thrust provides longer life than sleeve bearings commonly found in lubrication pumps

● The reversing feature, enabling flow in one direction only, has been perfected by Viking over four decades of experience with this design

● Standard pump has no pressure relief valve. Pressure relief valve option is available on the “A” and “AS” sizes. Viking recommends installing pressure relief in the system.

How it Works:This pump uses the internal gear pumping principle, but unlike normal internal gear pumps which have the crescent and idler pin mounted on the head (cover plate), this pump has an internal head mounted behind the cover plate. Each time the drive shaft changes direction of rotation, the internal head rotates 180°, changing the position of the crescent, to maintain flow in one direction only.

INLET CONDITIONS: The performance curves show “Based on 10 (or 15) In.-Hg.” which is Viking’s standard test condition. This is not the maximum vacuum capability of the pump.

NPSH (Net Positive Suction Head): The NPSHR (Net Positive Suction Head Required by the pump) is given in the table below and applies for viscosities through 750 SSU. NPSHA (Net Positive Suction Head Available in the system) must be greater than NPSHR.

For a complete explanation of NPSH, see Viking Application Data Sheet, AD-19.

FEET OF LIQUID (SP. GR. 1.0), VISCOSITIES - 38 SSU TO 750 SSU

FOR VISCOSITIES ABOVE 750 SSU (NPSHR data not available): The performance curves are based on 15 In.-Hg. While vacuums up to 20 In.-Hg. will not generally result in any loss of capacity, it is recommended that the suction line size and possibly the pump port size be increased to hold the expected vacuum to 15 In.-Hg. or less, when measured at the pump suction port. Vacuum above 20 In.-Hg. should be avoided. (Refer to “Engineering Data” Catalog Section 510 for information helpful in determining suction line size.)

MECHANICAL EFFICIENCY: The Mechanical Efficiency (expressed in percent) can be calculated by using the following formula:
