Armstrong 110116MF-303 H-53-3 LV Pump Less Volute

Balanced three-phase mechanical rooms can evaluate the Armstrong 110116MF-303 H-53-3 LV less-volute assembly with 1 HP power, 208 to 230 or 460 V operation, sealed SBA bearing construction, and ceramic-face mechanical seal.

The external thermal-overload requirement must be included in the motor-control plan. Cast bronze or engineered-composite impeller options affect component selection, while the less-volute arrangement requires existing volute compatibility, shaft fitment, and coupler alignment before replacement approval.

Armstrong 110116MF-303 Equipment Details

- The 1 HP motor establishes the listed power class for three-phase electrical coordination.
- 208 to 230 or 460 V operation requires confirming the available supply and motor connection.
- The less-volute format requires existing volute compatibility before ordering the assembly.
- A sealed maintenance-free SBA bearing identifies the documented bearing arrangement for service planning.
- The ceramic-face mechanical seal provides a specific sealing configuration for application review.
- External thermal-overload protection is required for motor-control and commissioning planning.
- Cast bronze or engineered-composite impeller options require exact configuration confirmation before purchase.

Performance and Application of Armstrong 110116MF-303

Industrial fluid transfer and balanced three-phase mechanical rooms are the listed applications for this assembly. The supplied information does not state exact flow, head, NPSH, pressure, temperature, or efficiency values, so the impeller option and existing volute must be matched to the required system duty.

Installation Requirements for Armstrong 110116MF-303

Confirm three-phase voltage, external thermal-overload protection, existing volute compatibility, ceramic seal selection, SBA bearing arrangement, coupler alignment, rotation, and service clearance before installation. The less-volute assembly should be evaluated with the existing pump housing and connected piping rather than as an isolated replacement.

Warranty and Service for Armstrong 110116MF-303

Armstrong provides a 30-Month Limited Warranty from date of manufacture for circulators, covering material and workmanship defects under normal use and service. Improper installation, maintenance, misuse, alteration, negligence, abnormal additives, and normal wear are excluded. SBA bearing and mechanical-seal condition should be included in service planning. Mulmotor provides product-information support before purchase.
