Four key sizes for drilling-fluid applications

The 3L4, 3L6, 3L8 and 3L10 are widely recognized progressive cavity pump sizes for drilling-related service. ACCA supports these applications with replacement pumps and components intended for demanding mud, bentonite and solids-bearing fluid duties. Final selection should be based on required capacity, pressure, fluid properties and operating speed rather than model designation alone.

3L4Lower-displacement drilling duties
3L6Common drilling and mud-transfer service
3L8Higher-capacity drilling-fluid duties
3L10Large-displacement drilling applications
Application Engineering

Select the size around capacity, pressure and fluid behavior

Drilling mud can change viscosity, density and solids loading as the operation progresses. Pump speed must allow adequate cavity filling while providing the required flow. Abrasive solids, differential pressure and suction conditions influence component wear and achievable operating range.

FlowRequired minimum and maximum capacity
PressureActual differential pressure
ViscosityMud properties across the duty
DensityActual drilling-fluid weight
SolidsConcentration and abrasiveness
DriveAvailable speed, power and control
