Product description
Technical data
The RA multi-line pump is a unique radial piston pump with
stackable pump elements The modular pump design allows Function principle radial piston pump with stackable
up to five pump elements, each with one, two or four outlets Operating temperature pumping elements
–15 to 80 °C, +5 to +176 °F,
A later outlet reduction or outlet extension is thus possible Operating pressure 10 to 63 bar, 145 to 915 psi
The displacement of all outlets from a pump element is depending on drive speed
adjustable by a common setting device, setting range and oil viscosity
33–100% Several different mechanical or electric Outlets 1 to 20
(max 5 elements with 1, 2 or 4 outlets)
motor drives are available Lubricant mineral- and synthetic-based oil,
25 to 2 500 mm 2 /s
Metering quantity per outlet 0,007–0,02 cm 3 /revolution
Features and benefits 0.0004–0.0012 in 3 /revolution
Output per outlet 0,07–36 cm 3 /min
