1.1 INTRODUCTION
Ruhrpumpen pumps of type J Line are horizontal, single stage, double suction, double volute radially
split case centrifugal pumps. J Line pumps offer various configuration options, with upper suction and
discharge flanges for the J and JD configurations and side suction and discharge flanges for the JS and

equipped with a single axial case cover while the JD configuration offers both axial and radial casing
covers. All J line pumps are designed to comply with the latest edition of API 610. These pumps are
designed for continuous duty pumping of various fluids with combinations of metallurgical, mechanical,
