Hand-Operated Hydraulic Pump
Hand-Operated Hydraulic Pump A hand-operated hydraulic pump kit (MTS part number 100-254-832) is an accessory for operating the grips. The kit includes the pump, with shut-off and release valves, a pressure gage, and hydraulic hoses for connecting the pump to the grips. The kit also contains an extra supply of hydraulic fluid. An appropriate grip supply with good pressure stability is required to safely operate hydraulic grips.
Note In order for the pump to operate, the reservoir end of the pump assembly must be higher than the output end (or at least the same elevation). 1. Mount the pump. The preferred location is on the base of the load unit. If you are using the hand pump with a Landmark Load frame, follow the instructions below to mount the hand pump. A. Lift the rubber work surface and remove the two screws holding down the metal work surface of the load frame (A). B.
D. Apply sufficient pressure to the grips and check for leaks at all fittings. Sufficient pressure will be determined by the gripping force specifications of the grip. E. After ensuring that all connections are leak free, open the pressure release valve to release the pressure in the grips. With the reservoir end of the pump pointed up, fill the reservoir with Quaker Quintolubric hydraulic fluid, or equivalent. If the level is ever low, add more hydraulic fluid.
Force versus temperature The following figure shows that the grip force rating for specimen temperatures up to 700°C is 67 kN (1292°F at 15,000 lb) is stable. The figure also shows that the force rating is reduced proportionately for specimen temperatures between 700°C and 1000°C (1292°F and 1832°F), with a maximum force rating of 8.9 kN at 1000°C (2000 lb at 1832°F). 66.7 kN (15 kip) 8.9 kN at 1000º C (2 kip at 1832º F) 66.

Install Specimen in the Grips Perform the following procedure to mount a specimen in the grips. Ensure that all grip parts are sufficiently cool before touching them. WARNING Specimen mounting is a potentially hazardous procedure because hydraulic pressure is applied to the system and actuator movement is required. This can cause personal injury. It can also apply damaging forces to the specimen, furnace, or to other fixtures. Use extreme care while performing the following steps.
Maintenance Maintenance for the hydraulic hand pump involves checking the fluid level in the reservoir of the hand pump occasionally by removing the pump’s reservoir plug and observing the level shown on the dip stick. If the level is low, add Quaker Quintolubric hydraulic fluid, or equivalent, only. Difficulty in obtaining or maintaining the pressure required for grip operation can be caused by low fluid level.
