SKGH Vertical Chemical Pump
The chemical variant of the inline body: stainless casing and impeller, 120 degree fluid rating, fitted directly into the pipe run.
Overview
What This Pump Does
The SKGH takes the vertical inline arrangement and puts stainless steel casing and impeller into it, for corrosive liquids with viscosity close to water. It is the pump to use where a chemical duty has to be fitted into an existing pipe layout.
Flow and head match the rest of the vertical range at 1.5 to 1500 m3/h and 150 m, with a maximum fluid temperature of 120 degrees Celsius.

Key Benefits
Chemical Duty Without Floor Space
Stainless Throughout
Casing and impeller both stainless steel, so the pump is not the first thing the chemical attacks.
Fits The Existing Pipe Run
Inline mounting means a chemical pump can be added without rearranging the plant room floor.
120 Degree Rating
Covers hot chemical transfer and circulation duty, not just ambient temperature service.
Seal Chosen For The Liquid
Mechanical seal with hard alloy faces, or packing gland, with elastomers matched to the chemistry.
Application Scenarios
Where It Is Installed
Chemical Circulation
Circulating corrosive process liquid inside a plant where the pipework is already fixed.
Treatment Chemical Transfer
Moving treatment chemicals with viscosity similar to water between tanks and process.
Hot Aggressive Liquids
Duties that combine corrosion with temperature up to 120 degrees.
Who It Is For
- Chemical plants retrofitting pumps into existing pipework
- Water treatment works with limited plant room space
- Surface treatment lines
- Engineers standardising on one pump envelope
Problems It Solves
No floor space for a chemical pump
The inline body is supported by the pipework, which is often the only way to add a pump to a full plant room.
Cast iron corrodes in service
Stainless wetted parts remove the corrosion failure mode from the pump body.
Different pumps for each duty
The vertical range shares one envelope across water, hot water, high temperature, chemical and oil duty.

Technical Data
Published SKGH data. Chemical selection depends on the specific liquid and concentration, so send both with the duty point.

Compared With Other Options
| SKWH horizontal chemical pump | Same chemical duty on the horizontal platform, easier to reach for maintenance but takes floor space. |
|---|---|
| Magnetic drive pump | Where no leak path at all is acceptable, a magnetic drive pump has no shaft seal, though at much smaller flows. |
Use Guide
Fitting A Chemical Pump Into An Existing Line
Confirm Compatibility
Chemical, concentration and temperature decide seal faces and elastomers before anything is ordered.
Support And Isolate
Brace the pipework either side, and fit isolation valves and a drain so the pump can be flushed.
Flush Before Opening
Always flush and isolate before maintenance, following the plant chemical procedure.
Check The Seal Drain
Any weep on chemical duty is a planned seal change, not something to monitor indefinitely.
Answers
SKGH Vertical Chemical Pump FAQ
