Advantages
Key Features
- Four-step flow/pressure selection (250/145/90/52 L/min at 2.5/4.5/6.0/6.0 MPa) matches coring, open-hole and casing conditions.
- Triplex single-acting piston design gives a smoother pressure curve than a duplex pump — fewer bit-pressure spikes.
- 83 % volumetric efficiency at rated speed.
- 15 kW electric motor, 380 V; diesel drive optional.
- 500 kg skid frame with 2.5 m suction lift — pairs with CH / UG / XY series rigs.
