A Huco Dynatork piston air motor was used by Blue Manta — an oil and gas services company — to replace a vane air motor.

Blue Manta — an oil and gas services company — used a piston air motor from Huco Dynatork to replace a vane air motor that was inefficient at working in extreme conditions, as well as being hard to repair and maintain due to its inaccessibility.

Blue Manta uses air motors to tension cable as it is lowered into an offshore or desert well. The vane air motor’s design made it hard to seal to protect against the ingress of salt water and sand. This same issue resulted in air being released instead of converted into motion.

The air piston from Huco Dynatork uses an integral rotary valve to supply air up to 100psi to each of three pistons in turn.

Torque is transmitted on start-up by the free floating pistons and adjusted via a pressure regulator, which creates high torque at a variable low speed.

Key benefits of product application

  • The design is easy to seal, so it is more reliable in hostile environments.
  • The motor traps compressed air in the cylinder, enabling maximum energy conversion.
  • Internal pneumatic porting is less sensitive to extreme temperatures.

Huco Dynatork is a world-class manufacturer of flexible couplings.

Whether the need is for high torsional stiffness, generous misalignment capability, high-speed operation or a capacity for operating in push/pull mode, Huco Dynatork can help. And if your requirements fall outside our standard range, we offer a customised service and cost-efficient small-batch production. 

Our range is highly comprehensive, comprising membrane and bellows high-performance couplings; Oldham and Uni-Lat general-purpose motion control couplings; Single-Beam, Multi-Beam and Step-Beam brands; and jaw/spider and double loop light power drive couplings. We also stock stainless steel and plastic universal joints.

Although the design and manufacture of couplings remains the cornerstone of our business, this is just one of the company's five main product groups. Huco Dynatork piston air motors is one of them, the only brand that can be used for precision motion control. 

Our quality hallmark is also impressed onto a huge range of power transmission and motion control components that have distinct design and performance benefits over other products in the market. In addition to an extensive choice of stock gears, racks, ground shafts and spline shafts, the product programme also includes the comprehensive BSA range of leadscrews and ballscrews.
