Description MJP Ultrajet 251HT (High Thrust) is a derivative of the MJP Ultrajet 251 - which has been in service world-wide for 10 years. The MJP Ultrajet 251HT has the same major installation dimensions and can be installed into a similar space envelope. Incorporating an efficient and robust axial flow pump, reverse and steering controls, it has many of the same design features as used in the current MJP Ultrajet range. The proven 4 and 5 bladed impeller design is less susceptible to mechanical damage than multi bladed designs. To achieve superior thrust, design improvements have been made to the intake and impeller of the MJP Ultrajet 251HT. This high thrust unit was specifically introduced into the MJP Ultrajet range for Seismic, Landing Craft, Cargo carrying, Commercial and Military Tow vessel applications, where high static thrust is a prerequisite. • Higher mid-range thrust for improved cruising speed and economy • Lower vibration and noise levels than other propulsion methods • Wide range of MJP-developed mechanical and electrical reversing controls Standard rubber impeller shaft bearing or optional composite bearing if dry running is required
