Glycol Pumps

Circulation Rate:

3 to 450 gph

Operating Pressure:

100 to 1500 psi


What is a glycol pump

A pump used for circulating glycol within a dehydration system.

A pump used to circulate amine within a desulphurizer system.

What is a Glycol Pump?


Features

No auxiliary power required system.

Eliminates need for level control and dump valve at

absorber

Low gas consumption

Completely sealed system prevents glycol loss

Only two moving assemblies

Hydraulic “cushioned” check valves with

removable seats of hardened stainless steel

Circulation Rates:

SC Series 8 - 200 gph

PV Series 3 - 450 gph

Animation


Pump trouble shooting

Loss of fluid circulation system.

Runaway pump

Hammering sound

Pump skips

Pump runs until normal temp. is reached

Erratic pump speed

Pump stalls

Leaking check valves

Valve body seal

Dart seal

Piston, piston rod seals

Suction Lines too small

Traps in wet glycol power piping send alternate slugs of glycol-then gas

Plugged lines in dehy stystem

Swollen O-rings

Plugged passages in pump

Blocked check valve

Loose actuator

Pump Trouble Shooting


Pump trouble shooting1

Gas blow-by to wet discharge system.

Excessive service required

‘D’ slide seal or port plates

Pilot piston seal failure

Poor Maintenance

Poor filtration

Chemical contamination
