- Pressures 300 to 420 bar (up to 1000 bar)
- Variable and fixed displacement control
- Piston assemblies, valve plates, servo valves
Wepuko DPX and DP Series Horizontal Triplex Plunger Pumps
Wepuko DPX and DP horizontal triplex pumps deliver flows up to 5000 l/min and pressures up to 1500 bar with ratings up to 1600 kW. Compliant with API 674 and ISO 13710, they handle process fluids and water hydraulics. Rugged construction ensures continuous plant duty.
- Series DPX 100, DP 200, DP 400, DP 500, DP 800
- Flows up to 5000 l/min, pressures up to 1500 bar
- API 674, DIN EN ISO 13710, EAC compliance
- Ceramic plungers, valve blocks, packings
Hydraulic Forging Presses and Direct PMSD Drives
Wepuko PAHNKE forging presses generate forces from 10 to 150 MN for open-die and closed-die forging of slabs and shafts. The PMSD direct drive with RX pumps controls ram speed and force without throttling valves. Turnkey packages integrate CNC and manipulators.
- Forging forces 10 to 150 MN (open & closed die)
- PMSD direct drive eliminating throttling valves
- Turnkey CNC systems and integrated rail manipulators
- Main cylinders, forging dies, power units
Industrial Descaling Systems and Water Hydraulics
Wepuko PAHNKE descaling systems remove oxide scale from hot steel and slabs with water pressure up to 400 bar. Engineered skids feature fast shutoff valves, high-pressure headers, and flat-spray nozzles. The process preserves roll life and metal product finish.
- Descaling water pressures from 160 to 400 bar
- Header delivery volumes up to 3000 l/min
- Fast shutoff valves, descaling headers, nozzles
- DP pump skids, duplex filters, check valves
Technical Diagnostics and Preventive Maintenance of Wepuko High-Pressure Pumps
Field engineering services provide routine maintenance, non-destructive testing, and vibration monitoring for Wepuko PAHNKE / Wepuko pumping units built to API 674 and ISO 13710 standards.
Field engineers carry out laser shaft alignment, plunger packing reconditioning, fluid manifold borescope inspection, and dynamic balancing of drive rotors.
Prior to returning units to full operating load following overhauls, pump fluid heads undergo hydrostatic proof testing, thermal alignment verification at rated operating temperatures, and multi-channel pressure pulsation logging.
Maintenance agreements and OEM component deliveries ensure maximum production uptime.
Installation, Laser Alignment and Commissioning of RX Radial Piston Pumps
Wepuko RX series radial piston pumps are mounted on rigid fabricated bedplates integrated with press power units. Nozzle load inspections utilize dial indicators to verify that external piping stresses on pump flanges remain zero during full torque tightening sequences.
Commissioning steps comprise rotational direction validation on decoupled motors, lube system flushing, reservoir priming with filtered hydraulic fluid, and regulated startup verifying rapid flow reversal without pressure surges.
Overhaul Procedures for DPX and DP Triplex Plunger Pumps to API 674 Standards
High-pressure triplex plunger pumps of series DPX and DP operating in continuous process injection and descaling service require systematic inspection of tungsten carbide plungers, crosshead guide clearances, and suction/discharge valve seats.
Major overhauls involve complete fluid head teardown, high-pressure chevron seal replacement, ultrasonic testing of eccentric crankshafts for fatigue defects, and hydro-testing of valve blocks. Bolt tightening follows calibrated torque sequences.
Engineering Support for Forging Press Complexes and Direct PMSD Hydraulic Drives
Wepuko PAHNKE hydraulic forging presses utilizing PMSD direct sinusoidal drive require scheduled electronic calibration of RX pump swashplate servo actuators and optical alignment of press guide columns. Engineers monitor fluid tank cleanliness and hydraulic filtration.
Service inspections evaluate anti-cavitation prefill line performance, thermal fluid stability, and synchronized rail manipulator tracking during open-die and closed-die forging cycles. All inspections conclude with detailed technical audit reports.
