Product Overview
The Parker Hannifin 3781050 F1-051-R is a fixed displacement bent axis piston pump from the renowned Parker F1 series. Engineers specify this pump when a compact, high-pressure hydraulic source is required for mobile and industrial circuits operating up to 350 bar (5,000 psi) continuous duty. With a displacement of 51.1 cm³/rev, the F1-051-R delivers substantial flow for boom, bucket, vibration, steering and auxiliary functions on heavy equipment.
Pioneer Mitra lists this exact catalog row — not a generic “Parker hydraulic pump” page — because procurement teams, rental fleets and export buyers search by part number. Our Delhi warehouse unit carries an original Parker nameplate manufactured in Sweden (2021 production lot). Photographs on this page show the nameplate serial, pump casting, SAE flange shaft spline and original Parker carton labelling.
Before you buy Parker 3781050 in India, we recommend confirming three critical fitment points: rotation direction (this is the R / counter-clockwise variant), shaft and flange geometry, and displacement class (51.1 cc/rev — not interchangeable with F1-041-R or F1-081-R without system redesign). WhatsApp us photos of your existing pump label; our technical desk confirms compatibility before proforma invoice.
This page supports buyers who need Parker F1-051-R hydraulic pump supplier support, Parker 3781050 Delhi stock verification, and Parker truck hydraulic pump replacements for fleets running compaction, lifting and material handling equipment.

Applications
The Parker F1 bent axis platform is widely deployed where robust flow and pressure stability matter more than variable displacement complexity. Typical hydraulic functions powered by an F1-051-R class pump include:
Always cross-check OEM equipment manuals. A pump with correct part number but wrong rotation or shaft geometry will cause immediate system damage. Our pre-dispatch WhatsApp video covers nameplate, rotation arrows and shaft close-ups specifically for this reason.

Compatible Systems & Cross-References
The F1-051-R displacement sits in the middle of the Parker F1 family. Related catalog rows buyers often compare:
- F1-041-R — 40.9 cc/rev (lower flow)
- F1-051-R / 3781050 — 51.1 cc/rev ← this page
- F1-081-R — 81.6 cc/rev (higher flow)
- Parker 3780364 — related F1 series row (enquire)
Do not substitute displacement classes without hydraulic engineering review. Flow, heat load and valve sizing all change. For Parker bent axis pump programmes spanning multiple sizes, see our Parker F1 series hub and bent axis pump guide.
