Griswold Model 811 ANSI B73.1 Process Pump. These instructions should be reviewed in their entirety and should be thoroughly understood prior to installation, operation or maintenance on the pumping unit. If there are any questions, contact either Griswold Pump Company or your local authorized Griswold representative prior to proceeding.
Installation, Operation and Maintenance Manual Griswold Model 811 WarnInG Serious injury or damage to the equipment could result unless care is taken to properly lift and support equipment. Receiving the Pump Care should be taken when unloading and handling the pump, especially with regards to rigging and lifting.
Griswold pumps have been designed and manufactured for safe and reliable operation when properly applied, operated and maintained in accordance with this instructional manual. Your safety is a primary concern for Griswold Pump, so we offer the following recommendations: General Safety Precautions Never apply heat to remove an impeller.
Installation, Operation and Maintenance Manual Griswold Model 811 INSTALLATION Installation The pump location should be clean, well ventilated, properly drained and allow room for maintenance and inspection. Trouble-free operation of a pump begins with proper installation with particular attention being paid to the baseplate and piping attachments.
Installation, Operation and Maintenance Manual Griswold Model 811 Installing and Grouting Base Note: Before the baseplate is installed, it is advisable to thoroughly clean the underside to enable the grouting to adhere to it. Do not use oil-based cleaners since grout will not bond to it.
Installation, Operation and Maintenance Manual Griswold Model 811 Suction and Discharge Piping A complete instruction for piping design is beyond the scope of this manual. A comprehensive guideline is available in the Hydraulic Institute Standards from The Hydraulic Institute, 9 Sylvan Way, Parsippany, NJ 07054, www.pumps.org. Note the following highlights: In general, all piping must be supported independently of, and line up naturally with, the pump flanges.
Page 11
Installation, Operation and Maintenance Manual Griswold Model 811 Suction Piping – Suction Lift Installations 1. Suction lines when operating under lift conditions must be absolutely free from air leaks. 2. Suction piping should gradually slope upward toward the pump. 3. NPSH available must be greater than the NPSH required by the pump.
Installation, Operation and Maintenance Manual Griswold Model 811 Alignment of Pump/Driver Shafts WarnInG Driver power must be locked out before beginning any alignment procedure. Failure to lock out driver power may result in serious physical injury. Note: Proper alignment is the responsibility of the installer and user of the equipment.

Installation, Operation and Maintenance Manual Griswold Model 811 As previously mentioned, pump and motor shafts need to be in alignment while they are at their intended operating temperature. When the shafts are aligned “cold” (at ambient temperature), we will intentionally position the motor shaft up or down in vertical parallel alignment to allow for thermal growth.
Installation, Operation and Maintenance Manual Griswold Model 811 Drivers Electric Motors Connect power supply in conformance with local and national codes. Line voltage and wire capacity must match the ratings stamped on the motor nameplate. cautIon Severe damage can be done to the pump if it is driven in reverse rotation.

Installation, Operation and Maintenance Manual Griswold Model 811 which is inserted into the oil sump in the bearing frame. In some instances, mechanical seals are flushed from the pump discharge through a heat exchanger. Cooling water is to be supplied to the “water” side of the heat exchanger.
Expect some drag from the mechanical seal. Pump Lubrication The standard lubrication for the Model 811 is flood oil. Lubrication options include oil mist, re- greasable bearings and greased-for-life bearings. See Appendix II for recommended lubricants. cautIon Pumps with flood oil lubrication are not filled with oil at the factory.
Installation, Operation and Maintenance Manual Griswold Model 811 If re-greasable bearings are supplied, grease fittings are furnished on the bearing frame. Prior to initial start-up, clean any dirt or foreign matter from the grease fittings. Remove grease plugs from the bottom of the frame. Pump grease through the fittings into each bearing cavity until fresh grease comes out of the relief ports.
Installation, Operation and Maintenance Manual Griswold Model 811 Systems on Suction Lift with Foot Valve See illustration at left. Note vent location above pump discharge nozzle. For initial start-up when discharge system is empty, it may be necessary to provide prime with an external, or outside, water source.

The Griswold Model 811 is an ANSI B73.1 design, which is back pull-out. The pumping assembly (back pull-out assembly) can be removed from service without disturbing the casing or the driver. An exception to this would be when a C-face adapter is used to support the electric motor and keep the pump and motor shafts in alignment.

Installation, Operation and Maintenance Manual Griswold Model 811 I. For Pumps with Component Mechanical Seals 1. Apply a bluing solution to the shaft sleeve and scribe a mark on the sleeve at the face of the seal chamber/stuffing box cover. This locates the seal setting reference point for the installation of the mechanical seal rotary unit.
Installation, Operation and Maintenance Manual Griswold Model 811 After the preliminary impeller adjustment is made (page 33): 1. Remove impeller leaving the shaft sleeve in place. 2. Re-install the impeller with its o-ring, being sure to tighten it firmly (tightens clockwise).
Installation, Operation and Maintenance Manual Griswold Model 811 ROUTINE AND PREVENTIVE MAINTENANCE A routine maintenance program can and will extend the life of your pump. Well-maintained equipment will last longer and require fewer, less expensive repairs. You should keep detailed maintenance records as this is helpful in diagnosing problems and the potential causes of problems.
Particular attention needs to be paid to this in order to maximize bearing life. The standard lubrication for the Model 811 is flood oil. Provisions are made on the pump for use of regreasable bearings and also for application of oil mist systems.
