Minar Hydrosystems Pvt. Ltd. (MHPL) was started to cater to specific customer requirements with respect to repairs and manufacturing of precision and critical cylinders, as an additional service to our clients. Over the years MHPL has manufactured special import substitute as well as customized cylinders for different customers for various applications. MHPL has helped its clients to reclaim critical cylinders by way of repairs where the only option left for the client was to purchase a new cylinder. Over the years we have developed our skills for the repairs & manufacturing of big cylinders in mining, cement as well as steel plants.

TUBES

The tubes are high quality steel internally HONED WITH MAX. ROUGHNESS OF 0.25 MICRON Ra with H8 bore tolerances. Roller burnished tubes with high toughness, wear resistance and low surface roughness are also available.

RODS

The rods are of high quality chromium plated alloy steel with minimum surface roughness of 0.25 micron Ra and plating thickness of 25 micron. The rods are ground to h8 tolerance. The hardest level chrome plated surface is 45-50 HRC.

HEAD CAP & PISTON

The head caps and pistons are machined to high degree of accuracy and surface finish to a common centerline for the cylinder body. To achieve critical surface finishes in the seal grooves, special tooling is used on CNC machines.

SEALS

MHPL enjoys excellent technical support from its sister concern ANK Seals which is a leading manufacturer of seals in India. With excellent R&D facilities for special sealing solutions, ANK Seals produces seals from world class elastomers and plastomers by machining as well as moulding technology.

CUSHIONING

Cushioning is incorporated in the cylinders to minimize the shocks and impacts at the end of stroke and extend its life. Incorporating cushioning in cylinders facilitates –

  • 1. Fast stopping of cylinders at the end of the stroke without damaging cylinder.
  • 2. Speed up the cylinder cycling time safely.
  • 3. Reduction of machine noise and maintenance.

STROKE

Stroke length is a customer specification. Stroke tolerance is 1mm upto 1000mm and 2.5mm for strokes exceeding 1000mm. Cylinder upto length 6500mm are available.

TESTING

Every cylinder undergoes – Dimensional inspection / surface roughness testing / chromium plate thickness testing / surface hardness testing / proof pressure testing / internal leakage test /endurance text (if asked) for the cycles of operations to be specified by you on in house 500T Test Rig.

SERVICE

MHPL have a separate fully devoted test department to provide after sales service. It has expertise in servicing and reclamation of cylinders to restore full life of your cylinder back again.
