Product Description

T6H T6H20, T6H29 of T6H20B,T6H20C,T6H29B, T6H29C, T6H29D T6H29DB and T7H T7H20, T7H29 T7H20B,T7H20C,T7H29B, T7H29C, T7H29D, T7H29DB piston & vane pump combined Hydraulic Parker Denison Hybrid pump.
The hybrid pump is a combination of fixed displacement vane pump B, C, D cartridges combined with a variable cartridge of PV20 or PV29 piston pump. The cartridges are driven by a common shaft without coupling in between they have a large common suction port and two or three independant outlet ports : One for the piston, one or two for the vane pump.
Both units fixed flow and variable flow having separated outlets allow simultaneous machine cycles eg : Mobile machine steering fonction working at the same time as the hydraulic cylinders boom functions.
GENERAL APPLICATIONS:
1. Check speed range, pressure, temperature, fluid quality, viscosity and pump rotation.
2. T6H pump case pressure should not exceed 0.7 bar (see datas).
3. Check inlet conditions of the pump, if it can accept application requirement.
4. Type of shaft : if it would support operating torque.
5. Coupling must be chosen to minimize pump shaft load (weight, misalignment).
6. Filtration : must be adequate for lowest contamination level.
7. Environment of pump : to avoid noise reflection, pollution and shocks.
8. Although the T6H pumps have fast off stroke compensator reponse, system relief
valves are recommended for safety considerations.
9. When constantly under pressure with no flow requirements, it is safer to flush the piston
pump. Three drains holes are there for this purpose.
Details regarding the choice of hydraulic fluid  
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG46 or VG68; to be selected: VG68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than115 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
