Key Features
The engineering highlights that make this pump a reliable drop-in replacement.
1
Hydraulic Match
Submersible motor and wet-end hydraulically matched to existing lift-station dimensions for seamless integration.
2
Continuous Submergence
Enclosed motor rated for continuous submergence (IP68), ideal for flooded wet wells and submerged environments.
3
Accessible Maintenance
Grease fittings positioned for service without removing the pump from the pit; tool-free volute access port, among the largest in its class.
4
Long-Life Bearings
High-performance bearing system designed for a 100,000-hour L10 life using non-proprietary bearings from multiple vendors.
5
Stiff Stainless Shafts
Shafts in 416 stainless steel, exceeding Hydraulic Institute stiffness standards with minimal deflection under load.
6
Flexible Seals
Single mechanical seal chamber designed to accommodate optional tandem or double seal configurations.
7
Hardened Wet End
Wear rings and suction covers in high-wear 420 stainless, hardened to 350–450 BHN; impellers enclosed or semi-open.
8
