Monarch ACE-100 End Suction Centrifugal Pump with C-Face Motor & Repair Parts
Monarch Industries ACE-100 (1 HP) End Suction Centrifugal Pump
The Monarch Industries ACE-100 (compatible with Franklin Electric FAC 100) is a robust 1 HP End Suction Centrifugal Pump designed for reliability and performance. Sitting in the sweet spot of the ACE series, the ACE-100 offers the perfect balance of power and efficiency for residential irrigation, water circulation, and industrial transfer applications.
Engineered with a heavy-wall cast gray iron casing and impeller, this pump is built to outlast plastic alternatives. It features a standard 1-1/2″ NPT suction port and 1-1/4″ NPT discharge, coupled with a high-performance C-Face motor. With mechanical seals rated for temperatures up to 200°F, the ACE-100 is capable of handling hot water circulation duties as effectively as cold water transfer.
Key Features of the ACE-100
- 1 HP Performance: Powered by a 3600 RPM, single-phase, industry-standard C-face motor (Frame 56J).
- Durable Construction: Both the casing and impeller are made from cast gray iron, providing superior resistance to wear and abrasion.
- High-Temperature Rating: Comes standard with a high-temp mechanical seal, allowing operation with fluids up to 200°F.
- Optimized Design: Features an accessible drain plug to prevent frost damage and facilitate easy priming air bleeding.
- Bearing Protection: A shaft flinger and large drain hole in the adapter bracket prevent moisture from pooling near motor bearings.
Common Applications
The ACE-100 is versatile enough for a wide range of uses:
- Lawn Sprinkling: Provides consistent pressure for medium-sized irrigation zones.
- Water Transfer: Efficiently moves water from cisterns, lakes, or holding tanks.
- Booster Service: Increases line pressure for wash-down or industrial applications.
- Hot Water Circulation: Safe for use in heating systems due to high-temp seals.
