Centrifugal Pumps

SKWY Horizontal Oil Pump

Built for petroleum products rather than water: gasoline, kerosene and diesel, with a published viscosity limit of 750 cSt.

Overview

What This Pump Does

The SKWY is the oil duty version of the horizontal platform. It handles petroleum products such as gasoline, kerosene and diesel oil, with the seal arrangement and materials chosen for hydrocarbon service.

Flow covers 1.5 to 1200 m3/h with a maximum head of 80 m, maximum viscosity 750 cSt and fluid temperature to 120 degrees Celsius, with drives to 160 kW.

Key Benefits

Why An Oil Duty Build Is Different

Viscosity Rating Published

A stated maximum viscosity of 750 cSt, so the selection is made against the oil rather than against a water curve.

Hydrocarbon Seal Arrangement

Mechanical seal with hard alloy faces or packing gland, with elastomers chosen for petroleum service.

Material Choice

Cast iron or stainless steel casing with cast iron, stainless or bronze impeller for the product being moved.

Large Flow Capability

Up to 1200 m3/h, which covers depot and terminal transfer as well as plant duty.

Application Scenarios

Where It Is Installed

Fuel Transfer

Moving gasoline, kerosene and diesel between storage and dispensing or process.

Depot And Terminal Duty

Higher flow transfer where head requirements are moderate and volume is large.

Plant Oil Circulation

Circulating oil inside a plant at temperatures up to 120 degrees.

Who It Is For

  • Fuel depots and terminals
  • Power plants and industrial fuel systems
  • Petrochemical operations moving refined products
  • Contractors building fuel transfer installations

Problems It Solves

Water pumps used on oil duty

Viscosity changes the curve and the power demand. A pump selected on a water curve will not deliver on oil.

Seal compatibility with hydrocarbons

Seal faces and elastomers are chosen for petroleum service rather than adopted from a water pump build.

Uncertainty about limits

Maximum viscosity, temperature and head are published, so the selection can be checked rather than assumed.

Use Guide

Handling Petroleum Products Safely

Check Viscosity Hot And Cold

Cold start viscosity can be several times the working figure, which sets the motor rating.

Bond And Earth

Follow the site procedure for static control on hydrocarbon transfer installations.

Prime Before Start

Ensure the casing is full. Dry running is as damaging on oil as on water.

Inspect The Seal Regularly

On fuel duty any seal weep is a safety matter, not a maintenance note.

Answers

SKWY Horizontal Oil Pump FAQ

Which products can it handle?

Petroleum products such as gasoline, kerosene and diesel oil, within the published viscosity and temperature limits.

What is the maximum viscosity?

750 cSt as published. Above that, a positive displacement pump such as the gear or progressing cavity line is the right choice.

What is the maximum head?

80 m on this model, with flow to 1200 m3/h.

Is an explosion protected motor available?

Motor specification follows the area classification of the installation. State the zone and the standard with the enquiry.

What temperature is allowed?

Up to 120 degrees Celsius on this data sheet.
