Frequently Asked Questions
QWhat is the maximum working pressure this pulsation dampener can handle?
This pulsation dampener is rated for a maximum working pressure of 7,500 PSI (51.7 MPa), making it suitable for high-pressure drilling mud pump systems used in oilfield operations.
QWhich mud pump models is this pulsation dampener compatible with?
It is compatible with BOMCO F1600HL, HH F1600HL, HH NB1600HL, and RGF1600HL, as well as all other mud pumps rated for 7,500 PSI working pressure. It also serves as a direct replacement for the overseas K20 7500PSI model.
QWhy is HNBR used as the bladder material?
Hydrogenated Nitrile (HNBR) offers superior resistance to high temperatures (up to 180°C), oil-based fluids, and highly corrosive drilling environments. This ensures consistent sealing performance and a longer service life compared to standard nitrile materials.
QWhat is the expected service life of this product?
Under normal drilling conditions with regular maintenance, the service life is 6,000 to 10,000 operating hours. Actual longevity may vary depending on fluid type, operating pressure, and maintenance frequency.
QDoes this pulsation dampener comply with any international standards?
Yes, this product conforms to API 7K standards. Third-party witness inspection reports are also available from recognized certification bodies including Bureau Veritas (BV), CCS, ABS, and SJS.
QWhat types of drilling fluids is this dampener designed to work with?
This dampener is designed to operate reliably with water-based, oil-based, and highly corrosive drilling fluids commonly used in oilfield drilling operations, providing broad compatibility across standard drilling programs.
