A wide range of sizes and material combinations complete the variety of the offered product.
Main design features
Fully designed according to latest edition of API 610 Std.
Pump shaft fully machined to respect the more restrictive run-out API limits.
As a standard, the rotor axial thrust is supported by a duplex oil lubricated ball angular contact type bearings.
Discharge column, line shaft and support column may consist of multiple sections, depending upon the pump setting. Discharge column mounted with a sliding fit through the sole plate to account for thermal expansions.
Renewable intermediate bushings, lubricated by the same pumped fluid or from an external source, are provided in correspondence of all column sections.

Griswold Vertical Turbine Pumps are available with two types of pump drives . . . vertical hollowshaft electric motor drive or right angle gear drive. Our turbine pumps offer you a choice of two types of lubrication . . . either a water lubricated line shaft or an oil lubricated line shaft construction.
To fit various applications, Griswold discharge heads are available either cast for above ground discharge or fabricated for various discharge configurations. Depending on pumping requirements, our pump bowls are available in 6”, 8”, 10”, 12” and 14” diameter.
Impellers available in the various bowl assemblies are of different designs and sizes. All impellers are precision designed, engineered and finished to give highest efficiency. Our impellers are made of high-strength bronze, machine, hand finished and dynamically balanced for top performance and long life.
We manufacture a large variety of impeller and bowl designs. This makes it possible for us to fit most any job from 60 to 3500 gallons per minute . . . low or high head . . . open or pressure discharge.

SPP's Lowest Life-cycle Cost Series of single and multi-stage Vertical Turbine pumps have been designed for longevity and incorporate many standard features, which facilitate ease of maintenance. A spacer coupling between the thrust bearing assembly and seal chamber allows a cartridge mechanical seal to be removed without dismantling the headpiece and removing the driver. Easily removable keyed muff type couplings connect all shafts, facilitating disassembly of the whole pump unit with minimal risk of damaging expensive component parts.
High-grade standard materials of construction and a rugged stiff shaft mechanical design coupled to state of the art hydraulics, offer unrivalled longevity and the lowest cost of ownership.
TYPICAL APPLICATIONS:
Water Treatment & Supply
River Water Extraction
Borehole Deep Well Extraction
Drainage & Irrigation
Cooling Tower Circulation
Process & Industrial utility duties
Petrochemical utility duties
Condensate Extraction
Sea Water lift

Magnetic drive turbine pumps MDK series
Leakage free, turbine pump
As is common with corrosion resistant pumps, this series uses the magnetic drive method, eliminating all problems caused by liquid leakage. Its pump characteristics include a small flow rate and high head.
Built-in self-priming valve
The inlet side of the pump contains a self-priming valve. Self-priming is actuated quickly after initial priming.
Superior corrosion resistance
The main parts are manufactured from SCS313 or SCS14 stainless cast, allowing the pump to be used for transferring organic solvents and various other chemicals.

Even turbine pumps belong to our product range. The advantages of the magnetic drive system and of high pressures are here combined. While the MDT series is best suited for incorporation in equipment, the MDK series is used as process pump for difficult liquids.

General
Magnetic coupled DICKOW-Pumps of the series PRM according to API 685 are heavy duty sealless pumps. The containment shell forms a closed system to separate the pumped liquid from the atmosphere by confined gaskets.
The equipment (including auxiliaries) is designed and constructed for a minimum service life of 20 years (excluding normal wear parts) and an uninterrupted operation of at least 3 years.
Applications
Magnetic coupled PRM-pumps improve plant and personnel safety and reduce maintenance costs, because 90% of these costs are caused by leaking seals. The PRM-pumps will handle nearly all kinds of liquids in the chemical and petrochemical industry, in refineries and industrial heating plants. Especially liquids which are toxic, flammable, bad smelling or which react on contact with the atmosphere, that means if no leakage is acceptable. For all these services, the containment shell replaces the double acting mechanical seal with its external flushing system and the related control equipment.
