INTRODUCTION 

 

811SP Series Manual Note 

This manual is intended to be a supplemental 

manual to the Griswold 811 ANSI Series 

manual. This manual covers the items specific to 

the 811SP Series pump line and for topics 

common to both the 811 ANSI Series and 

811SP Series pump lines (such as baseplate 

installation, coupling alignment procedures, 

etc.), see the Griswold 811 ANSI Series IOM for 

details, available on our website: 

https://www.psgdover.com/docs/default-

source/griswold-docs/ioms/811_iom.pdf. 

 

Safety 

Failure to read and comply with installation, 

operation and maintenance instructions found in 

the Griswold 811 ANSI Series manual will void 

the responsibility of the manufacturer and may 

result in bodily injury or equipment damage.  

The Griswold 811 ANSI Series manual and the 

811SP Series manual should be kept as a part 

of the permanent records for the pump and 

should be readily accessible as a reference to 

anyone working on the pumping unit.  

 

These pumps have been designed for safe and 

reliable operation when properly used and 

maintained in accordance with instructions 

contained in both manuals. A pump is a 

pressure containing device with rotating parts 

that can be hazardous. Operators and 

maintenance personnel must realize this and 

follow safety measures. Griswold Pump 

Company shall not be liable for physical injury, 

damage or delays caused by a failure to observe 

the instructions in the 811 ANSI Series and 

811SP Series manuals. 

 

Throughout the 811 ANSI Series manual, the 

words 

WARNING

CAUTION

, and 

NOTE

 are 

used to indicate procedures or situations, which 

require special operator attention. 

 

For full details, see the Griswold 811 ANSI 

Series IOM, available on our website:

General Safety 

 

Do not allow pump, piping or other 

components containing water to freeze.  

 

 

Freezing may damage the components, 

leading to possible injury or flooding

 

  Periodically inspect pump and associated 

components 

  Wear safety glasses when working on 

pumps 

  Keep work area clean, uncluttered and with 

adequate lighting 

  Ensure pump and components cannot roll or 

fall over, possibly causing bodily injury or 

property damage 

  Allow all system and pump components to 

cool before handling 

  Disconnect and lock out power before 

servicing the pump 

  Check explosion risk before spark inducing 

work, such as welding, using electric power 

tools, grinders, etc. 

Product Description 

The Griswold 811SP Series pump is a 

centrifugal single-stage self-priming pump which 

has all back-pull-out components in common 

with the Griswold 811 ANSI Series product line. 

The product line maintains consistent footprints 

and hold-down bolt patterns with the Griswold 

811 ANSI Series. The pump has a back-pull-out 

design, meaning that it is possible to remove the 

pump back-end without disturbing the case and 

piping, which can facilitate easier maintenance 

of the pump. Each case is designed with an 

integral priming chamber that supplies liquid to 

the impeller during pump priming, which allows 

the pump to draw a vacuum in the suction line, 

drawing liquid up the suction pipe and ultimately 

into the pump resulting in full prime.  

 

Since the 811SP Series utilizes the full back-end 

of the Griswold 811 ANSI Series pumps, the 

only components unique to the Griswold 811SP 

Series are the case and, if applicable, spacers to 

adjust for a larger pump centerline height.
