Product Overview
The Vaner assembly (valve assembly) of the mud pump is composed of the Vaner body, Vaner seat and Vaner rubber (sealing ring), and it is a key control component for controlling the suction and discharge of mud. The Van der assemblies produced by our company are forged from high-quality 20CrMnTi/8620H alloy steel, undergo carburizing and quenching heat treatment, and are equipped with high-wear-resistant polyurethane rubber. They feature extremely high impact resistance, wear resistance and corrosion resistance, and can operate stably under high pressure, large flow and harsh drilling conditions.

Performance features and advantages |
Four-ribbed/three-ribbed Vane assembly
(Four-Web / Three-Web) |
Ferritic: Carburizing and quenching of 20CrMnTi
Rubber: High-quality polyurethane (PU) |
API 4# ~ 8#
(Supports customization |
≤ 34.5 MPa
(5000 PSI) |
Oil-based and water-based mud
≤ 80℃ |
The classic multi-ribbed guiding structure features precise positioning, uniform force distribution and extremely high cost performance, and is widely used in conventional oil and gas drilling operations. |
Through-hole type/ribbed vane assembly
(Full Open Valve) |
Van der: 8620H / 20CrMnTi
Rubber: High-temperature and high-pressure resistant polyurethane |
API 4# ~ 8#
(API-4, API-5, API-6) |
≤ 52.0 MPa
(7500 PSI) |
High sand content/high viscosity slurry
≤ 110℃ |
There are no intermediate ribs to block it, and the flow area is large, effectively reducing the mud flow resistance and erosion. It is extremely suitable for high-pressure, deep well and complex formation drilling. |
Double-guided/top-guided Van der assembly
(Top & Bottom Guided) |
Vernite: 20CrMnTi alloy steel
Rubber: highly elastic polyurethane |
API 5# ~ 7# |
≤ 37.0 MPa
(5360 PSI) |
Common water-based/oil-based mud
≤ 90℃ |
The upper and lower dual guiding structure ensures a smooth switching process without eccentric wear, which can effectively extend the service life of the valve seat and the rubber. |
High-temperature resistant/anti-corrosion Van der assembly
(High-Temp / Acid Resistant) |
Vernite: Special alloy steel
Rubber: High-temperature resistant fluororubber/synthetic polyurethane |
API 4# ~ 8# |
≤ 55.0 MPa
(8000 PSI) |
Acidic and highly corrosive mud
≤ 150℃ |
Designed specifically for geothermal Wells, ultra-deep Wells and environments with strong corrosive media, it features excellent anti-aging and acid and alkali corrosion resistance. |

Ordering Instructions
When placing an order, please specify the model of the mud pump (such as F-1600) and the API specification number (such as API 6# or API 7#).
2. Please confirm the structural style (four-ribbed type or through-hole type without ribbed type) and the working condition pressure so as to be equipped with the corresponding material of Verne rubber.
