Features:

 

- Swashplate design Axial variable plunger pump for hydrostatic transmission in a closed circuit.
- The flow is proportional to the drive speed and displacement.
- As the swash plate angle increases from zero to its maximum value, the flow increases proportionally.
- When the swash plate passes through the neutral position, the hydraulic oil flow direction changes smoothly.
- Two pressure relief valves are fitted to the high pressure port to prevent overloading of the hydrostatic drive (pump and motor).
- The high pressure relief valve can also be used as a charge check valve.
- Built-in charge pump rushes current oil pump and controls variable use.

- Optional with coupling flange for direct cardan shaft drive

- Integrated boost pump for boost and pilot oil supply

- Flow direction changes smoothly when the swashplate is moved through the neutral position

- High-pressure relief valves with integrated boost function

- Boost-pressure relief valve

- Through drive for mounting of secondary pumps

- Swashplate design

Stainless Steel Cut Wire Shot AS Cut

Cut Wire Shot is a very important and popular Metal Abrasive.It is often utilized in shot peening processes when ferrous contamination of work piece is forbidden. As the most cost-effective one, the stainlesss steel cut wire shot, also named Stainless Steel Shot, is widely used for shot peening processes on stainless steel or inconel parts. When Blasting stainless work pieces or other metals need to be down as a pristine surface, stainless cut wire may be a very good metal abrasive to take into consideration. Stainless Steel Cut Wire Shot As Conditioned is usually used for shot peening processes on stainless steel or inconel parts. As for Longlived stainless steel cut wire shot, the minimum diameter could be 0.15mm and maximum diameter is 3mm. If you want, it could be bigger as your demand.

Concerning stainless steel cut wire shot, it has a very bright surface, maintains its shape longer then cast abrasives and it has a dust free surface. Stainless Steel Cut Wire is available as cut or conditioned and with various chemical compositions.The bulk density of stainless steel cut wire shot is very high and must be taken into consideration in relation to its use in equipment. Suitable equipment must be selected to convey stainless steel shot.

Generally, stainless steel cut wire shot could be classfied into two kinds. One is stainless steel cut wire shot as cut and as conditioned. And then, stainless steel cut wire shot as conditioned could also be divided into three small groups according to their different roundness and they are G1, g2, G3.
