PDF Hydraulic Pump Instruction Manual

Hydraulic Pump Instruction Manual. Thank you for purchasing a Hydraulic Hand Pump from Crystal Engineering. Hydraulic hand pumps provide a portable pressure source for calibration of high pressure gauges, recorders, switches and transmitters. The built-in variable volume provides a way to set the pressure precisely, regardless of how high the pressure is. There are two pressure ports on the pump. Mount a Crystal Gauge or Calibrator directly to the front of the pump, connect the spare port directly to the device being tested, and you have a complete field pressure calibration system. A 1m (3ft.) CPF high pressure hose, and CPF Female to1⁄4″ Male NPT is included, along with a convenient plastic bottle for hydraulic fluid. AInternal parts of the pump are made of Buna-N rubber, aluminum, brass and stainless steel. The pump can be used with oil, water, or other compatible fluids. Use of water will accelerate wear of “O” rings and some sticking of piston may result. The recommended fluid is any petroleum based hydraulic oil, light weight motor oil or mineral oil. Do not use brake fluid or synthetic oils; they may crack the polycarbonate reservoir or cause swelling or decomposition of the “O” rings.Connections: Your pump has two connections. A 1⁄4″ female NPT pressure port for a reference gauge or calibrator (figure 1) and a CPF female connection (figure 2). Always use PTFE (polytetrafluoro-ethylene) tape on the threads of any pressure fittings installed into the NPT port. Connect your reference gauge, or plug the 1⁄4″ female NPT port prior to priming or using your pump. As for the hose connection, we offer a wide variety of CPF fittings to. Fluid: Choose a fluid for your pump. We recommend any petroleum based hydraulic oil, lightweight motor oil, or mineral oil. Water can also be used, but it will accelerate the wear of “O” rings, and may cause some sticking of the piston. Do not use brake fluid or synthetic oils which may attack the polycarbonate reservoir, or cause swelling or decomposition of the “O” rings. Your fluid can be stored in the convenient plastic fluid dispensing bottle (supplied with the pump).
