Power End Parts
FH Petroleum manufactures mud pump belt pulleys for OEM and replacement applications, with established production experience supplying BOMCO mud pump manufacturing programs.
Our standard belt pulleys are primarily manufactured from HT250 gray cast iron. For higher or special technical requirements, forged alloy steel configurations can also be custom manufactured according to approved specifications.
Controlled machining, heat treatment and finishing processes are applied according to product requirements. OEM and replacement production can be supported from verified pump models, part numbers, technical drawings, dimensions or approved samples.
Product Description
The mud pump belt pulley, also commonly referred to as a drive sheave, is a key component of the mud pump power transmission system. It transfers power from the drive system to the mud pump through multiple V-belts.
For large mud pumps operating under demanding drilling conditions, pulley geometry and manufacturing consistency are important to reliable power transmission. The center bore, hub, mounting features and V-belt grooves must be manufactured according to the specified drive arrangement and dimensional requirements.
FH Petroleum manufactures large multi-groove mud pump belt pulleys for OEM production and replacement applications.


HT250 gray cast iron is the primary material used for FH Petroleum's standard mud pump belt pulley production.
Pulley bodies are manufactured according to the approved product design, with the hub, rim, spoke and multi-groove areas produced to the specified pulley geometry and technical requirements.
For applications requiring higher or special material specifications, forged alloy steel belt pulleys can also be custom manufactured according to approved designs and customer requirements.
Machining is a critical stage in mud pump belt pulley production. FH Petroleum machines key pulley features including the center bore, hub, mounting holes and multi-groove belt profile according to approved drawings and dimensional requirements.
Accurate machining supports correct pulley fit, belt contact, smooth operation and low vibration under the specified installation and operating conditions.

Depending on the pulley design and technical requirements, heat treatment and groove-surface hardening can be applied to improve wear resistance in the belt-contact area.
The required treatment is selected according to the approved product specification and application requirements.
The video below shows representative manufacturing stages from FH Petroleum's mud pump belt pulley production, including pulley-body preparation, machining, surface finishing, painting and packaging.
The footage includes different production batches and applications, followed by finished FH-manufactured belt pulleys prepared for assembly on an F-1600HL mud pump.
After machining and required production checks, belt pulleys proceed to surface finishing and painting according to the applicable product and customer requirements.
Finished pulleys are then prepared for handling, packaging and subsequent OEM assembly or replacement use.
