Buyer FAQs
Are balance discs and balance rings used in every pump?
No. These components are used in pump designs that include an axial-thrust balancing arrangement, commonly in multistage or high-pressure pump applications.
Can RF Machining select the balancing design?
No. RF Machining manufactures according to customer drawings or samples. Final hydraulic and mechanical suitability depends on the customer's pump design.
Can hardfacing or heat treatment be included?
Hardfacing, heat treatment, nitriding and grinding requirements can be reviewed and arranged through partner processes when specified.
