Hydraulic pumps for hydraulic tensioners and nuts

PP | FPT-C7 Series

  • PP series is ideal solution when connection to electric line is not available, so it is necessary to connect to the compressed air line (G”1/4 thread).
  • The air-oil intensifiers are featured with different multiplication ratios according to design maximum oil pressure.
  • FPT-C7 series are equipped with single-phase 4 poles electric motor, 230 V – 50 Hz, and solenoid valve 4-way-2 positions 24 VDC.
  • The oil-oil intensifier is designed to achieve a pressure ratio of 13:1 for pumps up to 2000 bar, and 16:1 for 3000 bar pumps.
  • The pressure regulating valve allows easy manual adjustment of the output pressure. A manual bypass valve is provided for pressure relief.
  • Compact design to reduce weight and facilitate transportability. Fixing holes are provided on the oil tank.
TESTO PP SITO ATTUALE High pressure air hydraulic pumps, the ideal solution for pressurization tests, material resistance, laboratory tests in general, stud tensioning operations, burst tests, testing of pressurized containers, bearing installation, actuation of hydraulic bolt tensioners or hydraulic nuts and anywhere you need a very high pressure. The standard version of the air hydraulic pumps are for oil circuits or in the water version on request. In the standard version the pneumohydraulic pump have pressure: 1500 bar – 2100 bar – 2500 bar – 3000 bar and 4000 bar. Air consumption is around 2,100 l / min. The supply pressure can vary from 1.8 to 7 bar. A feature of the pump is that following a pressure drop, the control unit automatically restores the pre-existing values. FPT – Fluid Power Technology designs and manufactures custom made high pressure pneumohydraulic pumps and units from 700 to 4.000 bar. For maximum customization and versatility. When standard production fails to meet customer requirements, FPT is able to design and produce hydraulic units according to customer specifications. The entire control unit can be completely designed according to the specific needs of the customer and the sector in which it operates. The range of accessories that can be equipped with the hydraulic system is very broad and includes transport cages, heat exchangers, various types of pressure gauges, special valves, protective cages and structures designed to specific customers and many others.   TESTO FPT-C7 (FPT-1500) SITO ATTUALE Single phase electric pump suitable for operating hydraulic bolt tensioners at 1500 bar. The project is based on a low pressure gear pump combined with an oil-oil pressure intensifier. The hydraulic pump is made in two fully automatic versions: one that allows the generation of pressure up to 1500 bar and two other models up to 2000 bar and 3000 bar. The panel control valve allows the comfortable setting of the outlet pressure. To download the data, the option with data logger is available; in fact, using an electric pump for bolt tensioners, it is possible to request as an optional the DATA LOGGER that allows the operator to download the data of the tightening performed and be able to subsequently analyze them. This model of control unit is extremely compact, light and suitable for use on wind towers or in environments with limited space available. FPT – Fluid Power Technology designs and manufactures special high-pressure pumps and hydraulic power packs from 700 to 4,000 bar. For maximum customization and versatility. When standard production do not meet the customer’s needs FPT is able to design and produce hydraulic power units according to customer specifications. The entire control unit can be completely designed according to the specific needs of the customer and the sector in which it operates.

Operations

  • Close and disconnect the pneumatic line when the pump is not in use, before breaking any hydraulic connection or intervening in any way in the system.
  • Always check both pressure gauge and hydraulic tensioning tool during operations. A pressure-step procedure is recommended.
