Sight Glass
A window into the line, so an operator can see product moving, colour changing or cleaning solution running clear.
Overview
What This Pump Does
Sanitary sight glasses in SS304 or SS316L, models SK-SG001 and SK-SG002, for DN15 to DN200 lines built to DIN, SMS, 3A, ISO and IDF standards.
Polished to Ra below 0.4 um with working pressure up to 1.0 MPa, vacuum on the low side and a temperature band of minus 5 to 95 degrees Celsius, with silicone, EPDM or fluoroelastomer seals.

Key Benefits
What A Sight Glass Is Actually For
Confirms Flow
An operator can see whether product or cleaning solution is moving without opening anything.
Shows The Rinse Running Clear
On a CIP return line it is the simplest confirmation that the rinse phase has finished.
Detects Air And Foam
Entrained air, foam and phase changes are visible immediately rather than inferred from instruments.
Line Standard Match
Supplied in the same standards and finish as the rest of the fittings.
Application Scenarios
Where It Is Installed
CIP Return Lines
Watching the rinse run clear at the end of a cleaning cycle.
Product Transfer
Confirming a transfer is running and the line is not empty.
Pump Suction Checks
Spotting air entrainment that would cause cavitation.
Who It Is For
- Dairy beverage and food plants
- Breweries
- Pharmaceutical production teams
- Operators and maintenance staff
Problems It Solves
No way to confirm the rinse is clean
A sight glass gives immediate visual confirmation without a sample or an instrument.
Air in the line goes unnoticed
Entrained air is obvious through a sight glass and invisible on a pressure gauge.
Transfers run dry
Operators can see when a vessel has emptied rather than waiting for the pump to tell them.

Compared With Other Options
| Flow instrument | An instrument gives a number. A sight glass shows what is actually in the line, including foam and colour. |
|---|---|
| Sampling valve | A sample tells you about one moment. A sight glass gives a continuous view without opening the line. |
Use Guide
Positioning A Sight Glass
Put It Where People Look
A sight glass behind a tank is useless. Position it where operators pass or where the panel is.
Light It
Good local lighting is what makes a sight glass genuinely useful on a dark plant floor.
Check Seals After CIP
Hot cleaning cycles age the seals. Inspect at planned intervals.
Keep The Glass Clean
Product film on the inside defeats the purpose. Include it in the cleaning route.
Answers
