American engineering heritage and Griswold pump manufacturing development

The history of American pump manufacturer Griswold spans more than seventy years of specialized experience engineering centrifugal hydraulic equipment.

Originating in California, the enterprise earned a global reputation as a premier supplier of process pumps for demanding chemical processing, petroleum refining, power generation, and water treatment.

Today, the Griswold brand operates as part of the multinational PSG division within Dover Corporation. Production activities are concentrated in Grand Terrace, California.

The modern manufacturing facility incorporates Hydraulic Institute test laboratories and automated computer numeric control machinery producing industrial ASME B73.1 process pumps.

ASME B73.1 chemical process end-suction pumps series 811 ANSI

The flagship Griswold 811 ANSI series features horizontal end-suction centrifugal process pumps engineered in strict compliance with the ASME B73.1 specification.

The equipment line encompasses more than thirty hydraulic sizes, providing accurate selection for duty points across pressure heads and flow deliveries when moving aggressive liquid solutions.

The back pull-out construction allows maintenance teams to extract the rotating element, power frame, and impeller for service without detaching the volute from facility piping or unseating the drive motor.

Precision balanced open impellers prevent solid debris accumulation and shield hydraulic flow channels against internal erosion.

Self-priming chemical process pumps series 811SP for sump transfer

Self-priming centrifugal process pumps Griswold series 811SP are designed for reliable fluid evacuation from below-grade sumps, chemical pits, and bulk storage vessels.

An integrated air separation chamber provides rapid initial priming and re-priming without requiring bottom foot valves in the intake suction piping.

A distinctive engineering advantage of the 811SP series is complete parts interchangeability of power frames, shafts, seal chambers, and mechanical shaft seals with the standard 811 ANSI pump portfolio.

This interchangeability reduces inventory overhead for chemical processing facilities and streamlines planned maintenance turnaround times.

Versatile industrial centrifugal water pumps series 850

The Griswold 850 series centrifugal pump line is engineered for broad industrial utility in cooling water circulation, filtration skids, municipal irrigation, and general industrial liquid supply.

Built with a heavy-duty ductile iron volute, the pump sustains continuous hydraulic pressure and provides four discharge orientation positions for piping flexibility.

A renewable lead-free bronze shaft sleeve protects the high-strength alloy steel drive shaft from electrochemical corrosion and physical wear caused by flowing fluids.

Precision machined suction wear rings preserve volumetric hydraulic efficiency and prevent internal bypass recirculation across decades of operational life.

Heavy-duty self-priming centrifugal pumps series H up to 25 feet lift

Industrial self-priming centrifugal pumps Griswold series H deliver exceptional water lift capabilities up to 25 feet (7.6 meters), surpassing ordinary single-stage centrifugal units.

The series sees widespread adoption in quarry dewatering, construction drainage, municipal lift stations, and commercial agricultural irrigation networks.

Each unit incorporates a removable suction flange fitted with an internal flapper check valve, preserving a prime liquid reserve inside the volute for immediate restarting after shutdown.

The enclosed bronze alloy impeller and wear-resistant internal diffuser ensure resilience against cavitation damage under elevated fluid velocities.

Dimensional ANSI parts interchangeability and rigorous PPAP validation

The Griswold interchangeability program ensures dimensional conformity and hydraulic compatibility for ASME B73.1 spare parts with legacy units from manufacturers including Goulds 3196 and Durco Mark III.

Standardized components encompass shafts, sleeves, impellers, power frame groups, and seal chamber adapters.

All manufactured components undergo multi-stage quality validation adhering to Production Part Approval Process PPAP protocols, featuring coordinate measuring machine inspection.

Components are available in ductile iron, 316 stainless steel, CD4MCu duplex alloy, and high-nickel alloys for severe corrosive industrial environments.
