(A battery pack is not included and must be prepared by the user.)● If the pump with a fully charged battery pack is used in combina- tion with a Riken S2-50 single-acting cylinder (200 kN x 50 mm stoke) and a 2 m hose, and if pressure is repeatedly raised to 70 MPa after the cylinder is extended 50 mm without a load, the numbers of operation cycles of the pump are as follows: Approx. 30 cycles with a Panasonic EZ9200S battery pack Approx. 70 cycles with a Panasonic EZ9L48 battery pack● We can also manufacture a "sealed tank specification" that does not require opening and closing air valves and worrying about oil leaks. ■BTP-21BMaximum operating pressure MPaModelHigh pressureLow pressureAt high pressureAt low pressureBTP-21B70BTP-21SKModelBTP-21BWhen the operating handle is turned clockwise to tighten and the pushbutton switch is pressed, the cylinder movesforward and stops when released.Remote control is possible due to a 3 m cable with a push-button. Pressing and holding the push button moves thecylinder forward. Releasing the button stops the movement of the cylinder. Pressing and holding the return buttonretracts the cylinder.BTP-21SKBTP-21BSold separatelyEZ9740 battery adapterSold separatelyEZ9L48 lithium-ion batty packDischarge volume cm3/min60■BTP-21B hydraulic circuit diagramOutlet port Rc7003/8Functions and operationsBattery pack(51)Battery pumpModel code structureTypeB:For single-acting cylinders (manual direction-control valve)SK:For single-acting cylinders (remote control)Series No.■BTP-21SK hydraulic circuit diagramTank oil volumeHydraulic oilISO VG321.7Push button switchOperating handle(210)(326)Effective oil Approx. weightvolumekgLL2 liOl6.51.38.1Air valve and refill port73MPa2.5MPa73MPa2.5MPaBattery PumpsBattery Pumps (BTP Series)*The approx. weight does not include the weight of the battery pack.■Explanation of functions and operationsSold separatelyEZ9200S nickel-hydrogen battery pack*The Panasonic EZ9L48 lithiumion batty pack stops operation below a certain voltage to prevent over discharge.66BTP-21B
