ITT Goulds Pumps
3430 Large Capacity, Single Stage, Double Suction Pump
The Goulds 3430 is a large-capacity, single-stage, double-suction pump with a horizontally split casing and dual-volute design. Combining axial and radial hydraulic balance with an i-FRAME bearing housing, it is engineered for long life and low maintenance across big water and process duties.
Product Benefits
- Fully balanced rotor: The double-suction, dual-volute combination balances the rotor both axially and radially, which is the foundation of the design's long-life, low-maintenance character.
- Top-half access: Suction and discharge nozzles are in the lower casing half, so inspection and rotor work require only lifting the top half while the piping stays put.
- Economical restoration: Renewable casing and impeller wear rings mean performance can be restored economically at overhaul.
Where It's Used
- Pulp and paper duties: In mills the 3430 serves mill water supply, shower service, and fan pump duty.
- Utility water services: It also covers cooling water, wash water, and fire pump applications.
- Broad industrial reach: The same platform covers a wide range of industrial, municipal, marine, and power-generation water services at large capacities.
Good to Know
- Wear-resistant materials: Standard construction pairs a ductile iron casing with a stainless steel double-suction impeller, Nitronic 60 casing wear rings, and a hardened stainless shaft, a materials set chosen for wear resistance in continuous water service.
- Imperial and metric builds: The pump is offered in both imperial (ASME) and metric (DIN) configurations, with raised-face ASME flanges or DIN flanges in several pressure ratings.
- Check flange standards early: Confirm the flange standard and rating against your site piping early, as this drives the configuration choice.
