Product Overview

▔▔

The Rexroth PV7 Series is a high-performance, variable displacement, pilot-operated or directly operated hydraulic vane pump designed for precise flow and pressure regulation in open-circuit industrial and mobile hydraulic systems. Positioned as a mid-to-high pressure standard variable displacement pump within Bosch Rexroth's hydraulic portfolio, the PV7 series provides efficient fluid power control by continuously adjusting displacement according to system load demand.

FAQ

▔▔

Q1: How do I verify the exact model code when replacing an existing PV7 pump?

A: Locate the metal nameplate riveted to the main housing of your current Rexroth pump. Note down the full model string (e.g., PV7-1X/25-30RE01MC0-05) and the 10-digit material code (MNR, starting with R or 0511...). Sending a clear picture of the nameplate to our technical team ensures an accurate 1:1 match or direct functional equivalent.

Q2: What is the recommended fluid cleanliness level for operating Rexroth PV7 pumps?

A: To ensure maximum service life and prevent premature vane or cam ring wear, the hydraulic fluid must maintain a cleanliness level of ISO 4406 Class 18/16/13 or better (equivalent to NAS 1638 Class 7). A suction line strainer and a high-efficiency return line filter (10 micron absolute) are strongly recommended.

Q3: Which types of hydraulic fluid are compatible with the standard PV7 pump?

A: Standard PV7 pumps with FKM (Viton) seals are fully compatible with mineral-oil-based hydraulic fluids (HL, HLP according to DIN 51524), synthetic esters (HEES), and environmentally acceptable hydraulic fluids. For water-glycol or special fire-resistant fluids, please consult our engineering department for seal modifications.
