Armstrong Vertical In Line Centrifugal Pumps - 4300 Series

Product Description:
Armstrong’s innovative 4300 vertical in-line pump realizes 60% savings in space compared to base-mounted pumps. The split-coupled design allows for the replacement of the mechanical seal without costly removal of the motor or pump from the piping. The high-performance outside-type mechanical seal combines advantages of multiple-spring balanced seal with premium quality, while the inside-type mechanical seal provides an economical alternative.

Product Specification:
• Design Features: 
1. Metric IEC72 standard motor designed for Vertical In-Line operation
2. Heavy cylindrical bracket with 360º register on each flange provides a grid union of pump and motor
3. Motor shaft run-out limited to 0.025 mm (0.001”) T.I.R. (Total Indicator Reading)
4. Axially split, spacer type rigid coupling permits seal maintenance without disturbing pump or motor.Lightweight high tensile aluminium, precision bored and designed to reduce bearing load.
5. Shaft deflection at mechanical seal limited to 0.025 mm (0.002”) T.I.R
6. Mechanical seal, accessible and easily replaceable (Outside multi-spring balanced mechanical seal illustrated.
7. Gland plate with flush connection ensures liquid at seal faces and positive venting of seal chamber
8. Dynamically balanced impeller assures smooth vibration-free operation
