  • Page 1 WELCOME TO VOGELSANG FACTORY TRAINING Best Practices for Installation of VX Rotary Lobe Pumps...
  • Page 2 Vogelsang Service Webinar | Storage Storage If you are not installing your new pump right away, there are steps you must take to ensure the pump remains in working condition when it comes time for startup.
  • Page 3 Vogelsang Service Webinar | Storage Short Term Storage 1. Flush pump with clean water (or water glycol mix), empty and allow it to dry. 2. Lightly grease bare metal surfaces and shafts. 3. Store the pump assembly in horizontal position in a dry area.
  • Page 4 Vogelsang Service Webinar | Storage Long Term Storage 1. Flush pump with clean water (or water glycol mix), empty and allow it to dry. 2. Store the unit in a low humidity environment, allowing excess moisture to evaporate 3. Open the cover plate of pump and spray a long-term preservative (e.g. SHELL ENSIS) on all bright pump internals and the inside of the cover plate.
  • Page 5 Vogelsang Service Webinar | Storage Recommissioning 1. Remove long-term rust preservative. 2. Drain the gear oil of the pump gear box to the rated oil level according to the O&M manual. 3. Drain the gear oil of the drive gear box to the rated oil level according to the O&M manual.
  • Page 6 Preparing for Installation Follow all best practices for safety when working on Vogelsang Equipment.
  • Page 7 Vogelsang Service Webinar | Safety Lockout & Tagout Important: 1. Follow all Lockout & Tagout procedure before any work is performed on the pump. 2. This sticker (or one similar on older models) came with your pump. Make sure your pump is ready to be serviced by performing steps 1-7.
  • Page 8 Vogelsang Service Webinar | Safety Over Pressurization Risk of injury from bursting components and liquid spraying out under high pressure. • The maximum operating pressure must not be exceeded at any time. • Observe and implement the recommendations in for installation in pipelines.
  • Page 9 Vogelsang Service Webinar | Safety Run Dry Even though our pumps are allowed to run dry from time to time, a brand new pump may develop friction during the break-in period. Friction could lead to heat and should be avoided.

  • Page 12 Vogelsang Service Webinar | Offloading Moving a Bare Shaft QD Pump Larger QD-Series pumps will have two lifting points. One is the same as the Q-Series and the other will be located on the outboard end of the pump. The fitting at the outboard end may be a ring or a tab depending on pump model.
  • Page 13 Vogelsang Service Webinar | Offloading Moving an Inline Assembly Moving a complete assembly will require a bridle to be composed of four cables or chains connected to the four slots located in the channel base. Do not use the lifting rings to move a completed assembly.
  • Page 14 Vogelsang Service Webinar | Offloading Moving a Belt Drive Piggy Back Assembly Moving a complete assembly will require straps to be threaded under the motor mounting plate. Make sure your straps are rated for the weight of the complete assembly.
  • Page 15 Installation...
  • Page 16 Vogelsang Service Webinar | Installation Mounting Flanges Most pumps come complete with a set of flanges. The flanges will be mounted to the skid to prevent damage during shipping. All hardware will be included such as hex bolts, washers and flange gaskets.
  • Page 17 Vogelsang Service Webinar | Installation Optional Grouting Our customers sometimes prefer to bolt inline assemblies to the pad and then apply grout above the flange to secure the pump and prevent any vibration. Our pumps are pulsation-free which means grouting is not a requirement but is an acceptable installation method.
  • Page 18 Vogelsang Service Webinar | Alignment Coupling Alignment Vogelsang offers two basic assemblies for most applications. The belt drive configuration must be aligned by verifying that both sheaves are aligned using a straight edge. Inline assemblies use a three part coupling device that must also be aligned to avoid any vibration or unnecessary wear.
  • Page 19 Vogelsang Service Webinar | Alignment Coupling Alignment for Inline Assemblies The alignment of the coupling must be periodically checked. If there is vibration during operation, alignment is sometimes the cause. Alignment can be verified by using a straight edge or other...
  • Page 20 Vogelsang Service Webinar | Alignment Surflex Coupling Alignment Check parallel alignment by placing a Parallel Alignment straight edge across the two flanges and measuring the maximum offset at various points around the periphery without rotating the coupling.
  • Page 21 Vogelsang Service Webinar | Alignment Surflex Coupling Alignment Check the angular alignment with a Angular Alignment micrometer or caliper. Measure from the outside of one flange to outside of the other at intervals around the periphery of the coupling. Don’t rotate...

  • Page 31 Vogelsang Service Webinar | Pressurized Oil Bottle Determining the Correct Pressure The proper pressure to be set varies. The pressure in the buffer chamber is determined by your normal suction and discharge pressure. A simple formula is used to determine the pressure. You need to know your suction and discharge pressure.

  • Page 36 Startup Direction of flow, Startup Checklist...
  • Page 37 Vogelsang Service Webinar | Direction of Flow Motor Driven Pumps Most pumps are configured with a single shaft electric motor as the drive unit for VX Series Pumps. The rotation of the shaft determines the direction of flow. The wiring configuration and/or VFD setting will determine which way the shaft will spin.
  • Page 38 Direction of Flow Direction of Flow Rotary Lobe Pumps are all reversible by design. Most Vogelsang pumps can easily be reversed on the fly. If your pump has standard or injection housings, the pump can run in either direction. However, our injection II housing is asymmetrical and should be run in the direction that the pump was configured for.
  • Page 39 Vogelsang Service Webinar | Wiring Direction of Flow The flow direction is initially determined by the way the motor is wired. Refer to the wiring diagram on the motor for instructions on which way to wire the motor.
  • Page 40 Vogelsang Service Webinar | Controls Control Panels Operating parameters are set by a certified controls representative per the motor specification. All panels must be set to constant torque.
