Armstrong 4300 Series 4300-10x10x13-100hp Vertical In-Line Pump

Description

Examine the split-coupled layout of the Armstrong 4300-10x10x13-100HP, a 10 x 10 x 13-inch vertical in-line pump with a 100 HP three-phase motor. Its outside balanced mechanical seal and fully enclosed, dynamically balanced impeller establish defined service and hydraulic-assembly details. District cooling, industrial plants, and high-rise condenser-water systems are listed applications.

Standard working pressure is 175 psi, while an optional 250 psi arrangement requires confirmation for the exact ordered unit. Official submittal data lists 100 HP availability at 1800 RPM with an ODP motor frame. Verify the selected motor enclosure, pressure configuration, pump curve, fluid requirements, and project duty before equipment is installed.

Key Specifications of the Armstrong 4300-10x10x13-100HP Vertical In-Line Pump

• The 10 x 10 x 13-inch size defines the listed vertical in-line frame for mechanical-room layout evaluation.
• A 100 HP three-phase motor establishes the supplied drive capacity for compatible district cooling and industrial plant systems.
• Split-coupled construction retains the motor during seal service, affecting maintenance clearance and installed-equipment access planning.
• An outside balanced mechanical seal identifies the stated seal arrangement for service comparison with alternative pump configurations.
• The fully enclosed dynamically balanced impeller defines the specified impeller architecture for this hydraulic pump assembly.
• Standard maximum working pressure is 175 psi, while optional 250 psi capability requires exact configuration verification.
• Official submittal data lists 100 HP availability at 1800 RPM with an ODP motor frame.

Hydraulic Performance and Application

The Armstrong Series 4300 vertical in-line pump is listed for district cooling, industrial plants, and high-rise condenser-water systems. Its frame size and 100 HP motor identify selection parameters, not a fixed operating point. Use the applicable pump curve to establish required flow, head, NPSH, motor selection, and pressure class against the completed mechanical design.

Installation and System Requirements

Confirm available three-phase electrical service, selected motor enclosure, operating pressure, piping layout, and approved duty before commissioning. Reserve clearance around the split-coupled seal area because the motor remains positioned during seal work. Support connected piping according to Armstrong instructions. Use the optional 250 psi configuration only when the supplied model is documented for that project pressure requirement.

Service and Maintenance Considerations

The split-coupled construction keeps the motor in place during specified seal service, so access around the coupling and seal area must be planned before installation. Follow official lockout, inspection, disassembly, and reassembly procedures for the installed configuration. The outside balanced seal and enclosed impeller require service practices based on Armstrong documentation, not generic maintenance assumptions.

Why Choose the Armstrong 4300-10x10x13-100HP

This configuration combines a 10 x 10 x 13-inch vertical in-line frame, a 100 HP three-phase drive, and split-coupled service access. Buyers can compare the outside balanced seal, dynamically balanced enclosed impeller, and 175 psi standard pressure rating against project needs. Confirm the optional 250 psi arrangement and the final motor enclosure through the approved equipment submittal.

Warranty and Support

Armstrong provides a 1-Year Limited Warranty for products other than circulators, covering defects in materials and workmanship under normal use and service. Coverage runs for twelve months from installation, but no longer than eighteen months from shipment. Normal wear and tear is excluded. Mulmotor provides product-information support before purchase and assistance with order-related questions.

Before Ordering the Armstrong 4300-10x10x13-100HP Vertical In-Line Pump

Before ordering, verify that the project requires a 10 x 10 x 13-inch vertical in-line frame with a 100 HP three-phase motor. You should confirm the approved pump curve, flow and head duty, motor enclosure, working-pressure rating, fluid requirements, and piping dimensions. Review clearance around the seal and coupling area, then confirm whether the 175 psi or 250 psi configuration applies.
