HP SERIES - HPRC - Pneumatic hydropneumatic pump

Product catalog summary

Technical Specifications:

Pneumatic operation (optional)
Pressure up to 700 bar
Oil flow up to 2.2 L/min
Tank capacity: 1.4 L
Compatible with standard pneumatic circuits (5/8 bar)
No lubricated air required
Low noise level (80 dbA)
Compact dimensions (295x115x170 mm)
Lightweight: 5 Kg
Heavy-duty construction
External maximum pressure valve
Standard air connection: 1/4"
Swivel connection (standard 3/8" NPTF)

Main Applications:

The HP-RC pump is suitable for all hydraulic applications, especially those requiring high pressures and controlled flow for precision operations.

Product Variants:

HP 250 RC: 7 bar air pressure, 250 bar oil pressure, 78/80 dbA noise, 5 Kg weight
HP 500 RC: 7 bar air pressure, 500 bar oil pressure, 78/80 dbA noise, 5 Kg weight
HP 700 RC: 7 bar air pressure, 700 bar oil pressure, 78/80 dbA noise, 5 Kg weight

Design and Functionality:

The HP RC pump is operated through a pneumatic device, replacing the pedal with two pneumatic pistons for oil delivery and release. It is compact with a 1.4-liter oil capacity, suitable for long cylinders. The pump is designed for high working pressures (250-700 bar) depending on the piston size, achieving oil flows of 2.2, 1.4, and 0.8 L/min respectively.

The swivel oil port connection facilitates easy hydraulic hose attachment. The pump can connect to standard pneumatic circuits and includes a replaceable internal air filter. It features an externally adjustable pneumatic relief valve to protect hydraulic components, and it operates even if not connected to a cylinder. A silencer ensures acceptable noise levels (max 78/80 dbA at 1 m distance).

Remote Control Option:

The HP RC model is available with remote control, allowing operation from a distance via a pneumatic control. It includes a button for delivery and another for release, connected through a 3-meter flexible hose for simplicity and efficiency.

HP SERIES - HPRC - Pneumatic hydropneumatic pump-2

La pompa HP RC di BELL prevede un azionamento di tipo pneumatico (opzionale). Al posto della pedaliera come nella versione HP, vi sono due pistoncini pneumatici, uno per la mandata e l'altro per il rilascio. Le caratteristiche di funzionamento sono le medesime del modello HP a pedale. Le dimensioni sono compatte con una capacita d'olio di 1,4 litri (unica versione disponibile per questo modello) sufficiente ad alimentare cilindri di lunga corsa. Questa pompa e stata progettata per alte pressioni d'esercizio: 250 - 500 fino ad un massimo di 700bar a seconda della dimensione del pompante interno...
