Frequently Asked Questions

Why choose a MAGNA1 instead of a MAGNA3?

The MAGNA1 is intended for users who need a high-efficiency, reliable circulator without advanced BMS features. Compared with MAGNA3:

• MAGNA1 offers simpler setup and operation with lower cost
• Ideal where only basic control modes are required
• Still provides major energy savings via PM motor and integrated drive
• Includes fault relay and digital start/stop input

Choose MAGNA3 when you need:

• Advanced flow estimation and heat-energy monitoring
• Full building management communication (BACnet/LON)
• Multi-pump cascade and advanced control functions

For straightforward HVAC circulation where simplicity and efficiency are the priority, MAGNA1 is usually the better value choice.

Is the pump maintenance-free?

Yes. MAGNA1 uses a canned-rotor wet-rotor design with no mechanical seal, eliminating routine seal replacement and providing very quiet operation.

Can this replace older fixed-speed pumps?

Yes — subject to hydraulic match. The variable-speed electronics in a MAGNA1 can provide major energy savings compared with a fixed-speed pump, but system duty and connection type should be confirmed before replacement.

Are union tails included?

This model uses G 2" union connections. Union tails or mating fittings are not included unless specifically shown in the product photographs.
