MiniBOOSTER Hydraulic Intensifier HC63-6.3-A

Product Description

The HC63- 6.3 – A is a compact high-flow unit, delivering up to 64.5 l/min on the high-pressure end. Similar to other miniBOOSTER models, it elevates supplied pressure to maintain a constant high outlet pressure, adjusting as oil is consumed. Weighing just 60.0 kg, it offers versatility with optional HP flange mounting and the ability to connect multiple units for increased flow capacity.

Functions Desctiption

The operational process is depicted in the function diagram. Initially, oil flows through the directional valve CV to the IN port, passing through check valves KV1, KV2, and DV to the high-pressure side H, ensuring maximum flow through the booster for fast-forward function. Upon reaching pump pressure on the high-pressure side H, valves KV1, KV2, and DV close. The oscillating pump unit OP maintains end pressure automatically, halting when the desired pressure is achieved. In the event of pressure drop due to consumption or leakage, the OP valve adjusts to sustain the end pressure.

Ordering an HC63

Ordering example of an HC63 with i = 4.0, DV incorporated and BSPP connections: HC63 – 4.0 – B – 1

Attention note!

The G-model is available in 2 variants, when ordering please specify accordingly:

Dynamic – low hysteresis: Ordering example of an HC63 with i = 4.0 RV incorporated and BSPP connections: HC63 – 4.0 – G – 1.
Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC62 with i = 4.0 RV with opening ratio x.x incorporated and BSPP connections: HC63 – 4.0 – G – x.x – 1.
