Siphon Drum Pumps


Style A	Style B

Since these pumps use suction to draw liquid out of your container, they continue dispensing once you get them started. They're often used with coolant and water.

5 gpm to 7 gpm Flow Rate—Adjust pumps with a 5-7 gpm flow rate for different dispensing applications.

Gauge Siphon Tubes


Style A	Style B	Style C	Style D

Also known as pigtails, these siphon tubes protect dry gauges from steam and high-temperature fluids. Add water to the tube to create a protective barrier between your gauge and process media.

NPT Male Connections

Style A

Style B

Style C

Style C—Style C requires less maintenance than Styles A, B, and D because the extra bends prolong water retention.
