In the Vertical Inline Pumps, the inlet and outlet are inline. This arrangement is typically used where space is limited such as onboard a ship, Generator Jacket Cooling etc. This type of pumps can be made to various designs which include spacer couplings to enable maintenance to be carried out without removal of motors reducing downtime. In monobloc designs, an inline pump will usually have a single shaft connecting the motor to the pump head meaning the motor bearings bear the full rotary load of the shaft during operation. This design of pump is better suited for short duties at full motor speed, and light duties. During maintenance the motor and pump must be disassembled with the mechanical seal refitted at the same time as motor fitting.
