RX Series Lightweight, Corrosion-Resistant Dewatering Pumps

Lightweight Stainless Steel Dewatering for Corrosive Environments

The BJM Pumps RX Series is designed for lightweight, corrosion-resistant dewatering using fully cast 316 stainless steel construction. These pumps are ideal for applications involving corrosive liquids, saltwater, washdown, and chemically aggressive environments where traditional cast iron pumps would fail.

With a compact design and top discharge configuration, the RX Series delivers reliable performance while maintaining portability and ease of use.

Built for Corrosion Resistance

RX Series pumps are constructed entirely from cast 316 stainless steel, including the motor housing, volute, and internal components. The cast construction eliminates welds, improving structural integrity and reducing corrosion risk at joints.

Standard FKM elastomers provide additional chemical resistance, with optional EPDM or Buna materials available to match specific application requirements.

Key Features & Benefits

• Full 316 stainless steel construction for corrosion resistance
