SIHI Ammonia Pumps
How many seals do you replace in your current ammonia pumps? Don’t forget to keep the oil reservoir filled, otherwise you’ll knock out another seal and cause a leak! Is this any kind of way to run a modern ammonia plant, especially in todays safety conscious environment?
Eliminate seals in your liquid ammonia pumps with ARESCO, Inc and Sterling-SIHI!
Sterling – SIHI of liquid ammonia pumps are simply the best pump made, period. Hermetically sealed with silicon carbide bearings, these pumps are built for long life, quiet operation, and they’re made to operate where other pumps fail. And no seals! Sterling-SIHI pumps are maintenance free! These durable pumps are runners, with many applications running for 10 years now and counting without a penny in maintenance. Can your pump do that?
The redesigned CEH pump is designed for trouble-free transfer and circulation of liquid refrigerants such as ammonia and fluorocarbons. The CEH design provides a compact unit which is leak proof, features a low requirement, and is cavitation resistant!
The seal-less design eliminates costly accessories required for pumps with double mechanical seals, since refrigerant cannot escape and air cannot contaminate the system.
The CEH also features a magnetically driven shaft. When most ‘canned’ ammonia pumps fail, the failure is normally in the motor. With the Sterling-SIHI CEH pump, the motor is a standard NEMA D Flange motor mounted externally. If the motor fails, you can replace it without having to pump down!
