RP series Rotor Pumps

1 ontact etails RP series Rotor Pumps Nomenclature Features Low noise Substantial reduction of the operation noise, by to db (comparison with aikin products), and improved sound quality are achieved by adopting noise reduction technology unique to aikin. ownsizing The integrated structure reduces the total length by approximately % in comparison with aikin conventional models, makes handling simpler, and is leading to downsizing the main machine. Low pulsation Pulsation has also been reduced by approximately % in comparison with aikin conventional models. High reliability The fully enclosed structure with no shaft protruding from the casing eliminates the possibility of oil leakage without an oil seal. In addition, the oil-cooled motor suppresses temperature rise of the coil and enables prolonged continuous overloaded operation. E compliant These models are best suited to integration into European Safety Standard (E) compliant equipment since they are equipped with a terminal box that satisfies the IP4 ingress protection grade and complies with international standards such as EN64-.

Since the vibration-absorbing rubber pad has no effect in vertical installation, be sure to secure sufficient rigidity on the mounting base and incorporate a structure that absorbs vibration. Insufficient rigidity of the mounting base may cause noise and vibration. Refer to Page N-8 for NR series rotor packs, i.e. hydraulic units equipped with an RP series rotor pump. - 8 Voltage code for the solenoid valve A: A V (/6 Hz), A V (6 Hz) : A V (/6 Hz), A V (6 Hz) P: 4 V 9 Motor output (See the motor specification table) Voltage specifications No designation: A V (/6 Hz), A V (6 Hz) : A V ( Hz) Y: A 8 V ( Hz), A V (/6 Hz) A 4 V ( Hz), A 4 V (6 Hz) A 46 V (6 Hz) esign No. (The design No. is subject to change) ontrol method III No designation: Without remote control system R: With remote control system Pump installation No designation: Foot support mount T: Vertical installation*

Note: * Some restrictions apply to the conditions of use when using the product at a pressure in the range 7 to 4 MPa {7 to kgf/cm }. JR-G(T) and JRP-G are recommended for the remote control system's relief valve. If the vent port is blocked, the pressure compensation structure does not work and the pump operates at a fixed pressure. In such a case, connect a relief valve at the discharge side of the pump. * The high quantity adjustment range may be restricted due to the setting for the low quantity range. See the graphs on Page -9 for details.

4 ontact etails Relationship between number of revolutions of the pressure adjusting screw and variation of discharge pressure (Kgf/cm ) Pressure change 4 Number of pressure revolutions Although the discharge pressure varies depending on the load conditions, the P pressure setting that serves as the upper limit for the discharge pressure can be set using the P valve's pressure adjusting function. Turning the clockwise (tightening direction) increases the P pressure setting. Turning the counterclockwise (loosening direction) decreases the P pressure setting. Excessive loosening of the pressure may cause oil to leak from the threaded section or parts to spring out. o not loosen the screw beyond the pressure adjustment range. The st to rd patterns correspond to the pressure adjustment range designation codes to. Relationship between the protruding length of the discharge rate adjusting screw and the discharge rate (pressure compensator control) The discharge rate can be set to the desired value by turning the discharge rate adjusting screw provided on the front cover. Turning the clockwise (tightening direction) decreases the discharge rate. Turning the counterclockwise (loosening direction) increases the discharge rate. The relationship between the discharge rage and the protruding length of the is shown below. Set the discharge rate to no lower than two-thirds of the maximum discharge rate, otherwise the suction capacity may be insufficient. Overtightening of the discharge rate may cause oil to leak from the threaded section. o not tighten the screw beyond the adjustment range.
