W+ Series (NEMA) - Centrifugal Pumps

W+ Centrifugal pumps are designed to achieve lifetime cost savings, lower energy consumption.

Key Features

W+ - Advanced Design for Performance and Reliability

W+ centrifugal pumps from SPX FLOW are designed to achieve total cost optimization with high efficiency and product dependability. They are installed in countless process facilities around the world helping producers meet stringent production requirements. The W+ Pump runs with the same rugged reliability you've come to expect from SPX FLOW products. Its versatile design helps increase process efficiency and maximize productivity while offering several innovative features such as:

Reliable and heavy duty design
Energy efficient
Quiet performance with minimal vibration
Superior shaft seal design
High pressure capability
3-A
Designed for CIP (Cleaning In Place) as well as SIP (Sterilizing In Place)
Suitable for wide variety of food, beverage and pharmaceutical products
Wide range of optional features available
Easy and cost effective maintenance

Seal Advantages:

Internal seal design optimizes cooling and lubrication of seal surfaces while the seal chamber is built to efficiently dissipate heat. Both work to reduce risk of "dry-running"
Directed flow assures thorough cleaning of seal areav
The stationary spring is located outside the product contact area to maintain cleanliness
Two sizes cover all models
Front loading seal simplifies maintenance: only the pump housing and impeller have to be disassembled, then the product seal faces can be replaced quickly from the front
Can easily be rebuilt into a double mechanical shaft seal for use with water flushing or with a barrier medium for aseptic applications
Double mechanical is mirror image of single: same seal faces and o-rings
