If you are using an HDB2,DGN4SS, HDB2,DN4SS or HDB2,DB4SS pump and are looking for a compatible replacement, the complete model reference is important.
Different HDB2 configurations may use different wetted and elastomer materials. Selecting a replacement only by the nominal 2-inch pump size may therefore result in an incorrect material configuration.
DJ PUMP currently offers compatible replacement options for selected HDB2 stainless-steel configurations, including HDB2,DGN4SS, HDB2,DN4SS and HDB2,DB4SS.
Table of Contents
Selected HDB2 Models We Can Cross-Reference
| Original Model Reference | Pump Description | Compatible Material Direction |
|---|---|---|
| HDB2,DGN4SS | 2″ Stainless Steel / PTFE | SS + PTFE configuration |
| HDB2,DN4SS | 2″ Stainless Steel / Neoprene | SS + Neoprene configuration |
| HDB2,DB4SS | 2″ Stainless Steel / Buna-N | SS + Buna-N configuration |
These model references are used for identification and compatibility cross-reference. Final configuration should be confirmed according to the original pump and actual operating conditions.
Why the Complete HDB2 Model Number Matters
“HDB2” identifies the general pump family, but the complete model reference provides more information for cross-referencing the correct configuration.
For example, the following references should not automatically be treated as the same pump configuration:
HDB2,DGN4SS
HDB2,DN4SS
HDB2,DB4SS
When requesting a compatible replacement, we recommend providing the complete original model number rather than only “HDB2.”
A pump nameplate photo is also helpful when available.
DJ PUMP Heavy-Duty Solid-Ball AODD Pump Design
DJ PUMP manufactures heavy-duty solid-ball metallic air-operated double-diaphragm pumps for demanding industrial fluid-transfer applications.
When cross-referencing an existing pump, the final configuration should be evaluated according to factors such as:
- Wetted material
- Diaphragm and check-valve material
- Fluid name
- Fluid temperature
- Viscosity
- Solids
- Required flow
- Required discharge pressure
- Connection requirements
A compatible replacement should be selected according to both the original pump construction and the actual application.
