Values from the Veljan Motor Catalogue (sections A and B). Maximum differential pressure and maximum speed must not be reached at the same time. Intermittent duty values (max 10% of every minute) are given in the catalogue. Maximum inlet pressure: 224 bar (AVMP, AWMP), 300 bar (MSA, MTAP, MVAP). For MSA-125 the catalogue continuous torque value (275 N·m) is inconsistent with neighbouring sizes and is not shown.

How the Veljan code is built

Series and size: for example AVMP-100 (nominal displacement 99 cm³/rev)
Shaft: M (25 mm), E (1″ cylindrical), S (splined), T (tapered); on the MS/MT/MV series also P, U, D, 6S, TX
Rear ports: suffix RP; external drain: suffix X
4-hole flange for AVMP and AWMP: suffix 4; unpainted version: N
Version with UNF ports: code IMA0005 (MS), IMA0004 (MTAPC), IMA0012 (MVAP)
Tacho drive: option TA on MS, MT, MV

Operating conditions from the catalogue

Fluid: mineral oil with anti-wear additives, viscosity 35 mm²/s at 50 °C, minimum 13 mm²/s
Oil cleanliness ISO 19/14, filtration 25 micron or better
Ambient temperature from −30 to +90 °C; operating temperature from +30 to +60 °C, maximum +85 °C
High-pressure shaft seal: drain not required in most applications
Below 10 rpm consult our technical department

Veljan orbital motors: frequently asked questions

Are Veljan orbital motors equivalent to Danfoss OMP, OMR, OMS, OMT and OMV?

Yes, according to the Veljan/Adan cross reference table: OMP corresponds to AVMP, OMR to AWMP, OMS to MSA, OMT to MTAP and OMV to MVAP, with the wheel (W) and short flange (S) variants. Before replacement we check flange, shaft, ports and displacement with you.

What changes compared with the Danfoss motor?

The code and, on some sizes, the nominal displacement: for example AVMP-75 is 79.2 cm³/rev against 77.8 for the OMP, MVAP-400 is 382 against 400.9 for the OMV. It is worth checking the speed and torque your system requires.

How do I order a Veljan motor to replace my Danfoss?

Send us the Danfoss code (for example 151-0302) or the nameplate code, with shaft type, flange, ports and quantity. A technician will give you the matching Veljan code.

What is the difference between AVMP and AWMP?

They are the two spool valve families equivalent to OMP and OMR. In the catalogue AWMP reaches 175 bar continuous (sizes 75–125) against 140 bar for AVMP, with continuous torque up to 360 N·m.

How soon do I receive price and availability?

Who is Veljan?

Veljan Hydrair was founded in 1965 in Hyderabad. In 1974 Denison Hydraulics India was established, with technical and financial collaboration with the Denison division of Abex Corp. (USA); the company later joined the Swedish Hagglunds group and became independent again in 1994. Since 2010 it has been called Veljan Denison Limited and manufactures pumps, motors, valves and power systems. Source: veljan.in/about.
