Griswold’s 811 Series ANSI Centrifugal Pumps Offer a Versatile Range of Seal Options
As one of the world’s leading manufacturers of ANSI centrifugal pumps, Griswold Pump Company has developed its 811 Series ANSI Pumps to offer end-users the flexibility, durability and performance needed in a wide range of fluid-handling applications.
Griswold’s 811 Series
As such, Griswold has designed its 811 ANSI pumps to be compatible with a broad range of options and upgrades that tailor their handling and performance to meet virtually any fluid-processing operation.
One of these areas is in the seal chambers. The seal chambers of Griswold 811 pumps have been engineered to provide an optimum seal environment for heat dissipation, solids, entrapped air and vapor. These oversized seal chambers feature increased radial clearances between the mechanical seal and seal chamber wall to provide better circulation of liquid to and from seal faces. The seal chambers are available in three styles: standard bore, which is ideal for packing or mechanical seals handling mild fluid at ambient temperatures; large bore, which can handle solid greater than 10% (when used in conjunction with a close clearance throat bushing and external flush) with a radial clearance that ensures improved liquid circulation, lubrication and cooling; and tapered bore, which services 10% solids or fluids containing entrained air or vapors thanks to its self-draining and –venting design.
Additionally, Griswold’s broad selection of seals can accommodate most any fluid and temperature up to 500-degrees F for chemical, petroleum, pharmaceutical and general industry applications. Options include cartridge or component, single or double, inside or outside, and balanced or unbalanced seals or conventional packing. Finally, Griswold offers ANSI B73.1 seal-flush and cooling plans that control emission levels, improve lubrication and cooling of the seal faces, and reduce pump downtime.
