A drive system for a fluid displacement pump includes an electric motor, a drive coupled to the rotor at a first end of the electric motor, a pump including a fluid displacement member mechanically coupled to the drive, and a controller configured to control a level of power to the electric motor based on a pressure setting set by a user. The electric motor includes a stator and a rotor disposed on an axis. The drive coupled to the rotor converts the rotational output to a linear, reciprocating input to power a pump.

A road taping machine is configured to unspool road marking tape from a spool and tamp that tape onto pavement via a tamping roller. Tape is cut using a blade assembly, and aligned with several alignment rollers. A pivot arm permits a subset of the alignment rollers to displace, allowing slack in the tape to be taken in during cutting such that taping can occur continuously, despite cuts. The spool is housed on an axle anchored to a support arm that can be actuated between an elevated position for loading, and a depressed position for taping. A taping section of the machine is laterally displaceable relative to a drive section via a displacement plate, to permit taping of laterally remote locations. The machine can support multiple spools, including spools with tape paths that bypass the blade assembly.
