Page 8: How It Works-Internal Gear Technology
How It Works—Internal Gear Technology The V SERIES GEAR PUMP is a rotating, positive displacement pump. These drawings show the flow pattern through the pump upon its initial rotation. It is assumed that the pump has no fluid in it prior to its initial rotation. -
Page 9: Suggested Installation & Operation
Suggested Installation and Operation V Series gear pumps are designed to meet the performance requirements of even the most demanding pumping applications. They have been designed and manufactured to the highest standards and are available in a number of different sizes to meet your pumping needs. - Page 10 V Series gear pumps are positive displacement pumps; as such, care must be used in protecting piping and components used in your system. Pumps equipped with an internal relief valve are designed to protect the pump only. A system relief valve should be installed along with the pump's internal relief valve.
- Page 11 PRESSURE RELIEF VALVES • V Series pumps are positive displacement pumps, which means the system must have provisions for pressure relief protection, such as a relief valve mounted directly on the pump or inline with the system. Alternatively, the system can be installed with a torque-limiting device or a rupture disk.

Page 12: Maintenance
Maintenance GENERAL MAINTENANCE CLEANING: V Series pumps must be maintained and kept as clean as possible. This will allow for quick inspection, adjustment and repair work. LUBRICATION: Use multi-purpose NLGI #2 grease on all lubrication fittings every 500 hours of operation. Do not over-grease. - Page 13 CARTRIDGE TRIPLE-LIP SEAL MAINTENANCE Blackmer offers a cartridge triple-lip seal as an alternative for packing. The seal comes pre-lubricated with Magnalube high- temperature grease. Do not remove the plugs from the gland or attempt to install flush lines because this could cause the grease to be lost.

S E C T I O N 7 Reassembly WET END ASSEMBLY Clean all parts thoroughly before assembly. Install the RBS bushing. If the bushing has a lubrication groove, install the bushing with lubrication groove facing towards the bottom of the RBS. If applicable, align the radial lubrication hole on the bushing with a grease hole on the RBS. For 55, 133 and 254 size pumps, attach the rear plate and gasket to the case. - Page 16 TABLE A – HEAD GASKET SETS Pump Models Starting Gasket Set Gasket Set Provided V2-55 1 - .006”, 1 - .015” 2 - .006”, 1 - .015” V2-133, 254 & 423 1 - .006”, 1 - .015” 1 - .006”, 2 - .015” TABLE B –...
