**Atos PVPC axial piston pumps**Variable displacement, open circuit, with mechanical or proportional electro-hydraulic controls.

Interfluid, one of the main partners of Atos, is proud to offer a wide range of Atos PVPC series axial piston pumps. Designed for installations in open circuits, they are ideal for applications that require operations at medium and high pressures.

Available types:

LQZ: model with a load-sensing system and proportional flow control in an open loop, regulated by an external electronic signal sent to the pilot proportional valve driver.
PERS: variant with integrated digital P/Q control in a closed loop, enriched with a sequencing module. It can reduce the minimum pressure at the outlet line to almost zero values.

Thanks to the strong collaboration between Interfluid and Atos, the PVPC series axial piston pumps are an advanced and efficient solution for industrial automation needs.

Data from Atos table A160 rev. 25.1, ISO VG 46 mineral oil at 50 °C. Peak pressure for max 50 ms. The code 5090 corresponds to an actual displacement of 88 cm³/rev. SAE J744 flange as standard, ISO 3019/2 on request (keyed shaft only).

Mechanical controls (table A160)

C – manual pressure compensator
CH – manual compensator with unloading (12 or 24 VDC coil)
R – remote pressure compensator (not for size 6)
L – load sensing (pressure and flow)
LW – constant power, adjustable from 4.5 to 185 kW depending on size

Proportional controls (table AS170)

CZ – open loop proportional pressure control
LQZ – proportional flow control, load sensing (not for size 6)
PES – closed loop p/Q control with on-board digital driver
PERS – as PES, with sequence module that brings delivery pressure close to zero

Frequently asked questions

What is the difference between PVPC with mechanical and proportional controls?

The mechanical versions (C, CH, R, L, LW) regulate pressure, flow or power with hydraulic compensators. The proportional versions (CZ, LQZ, PES, PERS) receive an electronic signal: PES and PERS have an on-board digital driver with closed loop p/Q control and fieldbus interfaces.

Which displacement should I choose?

Sizes range from 29 to 160 cm³/rev. Sizes 3029, 4046 and 5073 work at 280 bar continuous, size 6140 at 350 bar; max speed drops from 3000 rpm (size 3029) to 2000 rpm (size 6160).

What data is needed to request an Atos PVPC pump?

Send us the Atos code or the data of the pump you use today: we check displacement, control type, SAE J744 flange (or ISO 3019/2 on request) and shaft.

Do you repair Atos PVPC pumps?

Yes. Interfluid has been an authorised Atos Service Center since 2006: we recondition, inspect, repair and test Atos components with original spare parts. PVPC-PERS pumps are assembled in-house.

How long does it take to receive price and availability?

A technician replies within 24 working hours.

Can't find the code you need?Send us the Atos code or the data of the pump you use today: we check displacement, control, flange and shaft and propose the correct PVPC.
