RHA — Insert Pump
Go-to insert pump for standard service. Balanced clearances and coatings for everyday rod-lift.
View RHA specs →
Insert (RHA/RHB/RWA/RXB) and tubing (TH) pumps built for heat, sand and gas. Tight fits, clean geometry, traceable QA — and quick access to common sizes.
White Star’s API-11AX pumps are engineered around real well conditions: abrasive fluids, gas slugs, paraffin and crooked holes. We control clearances, finishes and metallurgy to keep stroke smooth and sealing repeatable — so your crews spend less time on retrievals and change-outs.
Go-to insert pump for standard service. Balanced clearances and coatings for everyday rod-lift.
View RHA specs →
For harsher wells: upgraded fits and wear surfaces; stable sealing under sand and gas cut.
View RHB specs →
Application-driven geometry and surface finish to maintain volumetric efficiency longer.
View RWA specs →
Designed for heavier solids and deviated holes; prioritizes stroke smoothness and sealing.
View RXB specs →
High-reliability tubing pump for deeper or abrasive wells. Serviceable design for faster turns.
View TH specs →Dimensions and options per API-11AX. Clearances, finishes and coatings are selected to match your fluid, gas and solids profile.
