Application detail
Designed around plant conditions.
Paired with nitrogen accumulator banks for instantaneous pulsation dampening during tramp rock transit, with low-friction bronze-filled PTFE seals to prevent stick-slip during micro-movements.
Final bore, stroke, mounting, material and seal selection are confirmed against the approved drawing and operating duty.
