Page 4: Pump Identification
Pump Identification Each pump has a unique serial number machined into the gearbox and stamped on the rotor housing. The type of pump is further described by the series number machined into the gearbox, i.e. 5000, 4000 or 3000. A pump may be described by a part number, as shown below, that indicates its features. - Page 5 G.

Page 8: General Description
1.2 General Description UNIBLOC-PD is a positive displacement rotary lobe pump. It may be supplied with a drive unit (figure 1.0) or without a drive unit (figure 1.1). When supplied with a drive unit it is called UNIBLOC-PD ASSEMBLY. Figure 1.0 indicates various parts of an assembly. -
Page 9: Before Start-Up
2.0 Before Start-Up QUICK CHECK LIST A. Are pump and motor alignment within proper tolerances? B. Do motor and pump gearboxes have adequate amounts of oil? C. Has the piping to the pump been installed correctly? D. Has the system and all pipes been flushed and cleaned of all debris including weld slag and particles resulting from polishing and grinding? 2.1 Pump Head Remove the front cover and make sure that no particles are trapped inside the rotor housing. -
Page 10: Pipe Layout
2.3 Pipe Layout When connecting pipes to the pump, make sure they are well supported, as the pump is not meant to serve this purpose. Keep in mind that pipes filled with liquid are very heavy. WRONG RIGHT 2.4 Port Positioning UNIBLOC-PD is designed to accommodate both vertical and horizontal product through-puts. -
Page 11: Alignment And Mounting Suggestions
2.5 Alignment and Mounting Suggestions If a PTO pump shaft style is used, it is imperative that the pump and motor are properly aligned before operating. Misalignment can lead to excessive wear and can cause the coupling to rupture. It can also create abnormal stresses on bearings and gears.

Page 12: Shaft Seal Service
3.0 Shaft Seal Service To aid in the removal and installation of the shaft seals, plastic mounting sleeves that are the same diameter as the shafts at the seal area are available. The mounting sleeves also protect the seals from the shaft splines. -
Page 13: Single Mechanical Tm Seal
3.2 Single Mechanical Seal This seal comes with different seal face combinations. (See drawing G812B for details.) Maximum shaft rotational speed for this seal is 2.4 m/s (7.8 ft/s) or 800 rpm and the maximum service pressure should not exceed 15 bar (220 psig). Maximum and mini- mum temperature limits are +160°C (320°F) and -15°C (5°F). -
Page 14: Seal Installation- Final Steps
3.3 Seal Installation- Final Steps See section 4.4 for torque limits. If not part of the shaft seal assem- bly, slide the plastic mounting sleeves over the splined ends of the shafts. Slide on the rotor housing (1) tap it with a rubber mallet to seat it properly on the dowel pins (20). -
Page 15: Gearbox Maintenance And Service
180°C (356°F) high temperature lubricant and seals must be used. For such cases, con- tact Unibloc-Pump or an authorized service center for an adequate service schedule. Before proceeding with the following steps, DISENGAGE POWER TO THE HYDRAULIC OR PTO MOTOR. If the pump is connected to piping, depressurize the system and close valves on both the suction and discharge sides to isolate the pump from the rest of the system. -
Page 16: Gearbox Assembly
4.2 Gearbox Assembly The following steps for assembly assume that the pump has been completely disassembled. Make sure all parts are clean and free of debris before proceeding. New oil seals are required to complete the assembly of the gearbox. 4.2.1 Assembling the Gearbox Insert the shim rings (11a) into the... -
Page 17: Lubricants And Gearbox Volumes
4.3 Lubricants and Gearbox Volumes UNIBLOC pumps come supplied with a synthetic oil, MOBIL 1 15W-50, applicable for service temperatures in the range of -23°C (-10°F) to 221°C (430°F). The following is a list of other synthetic lubricants that may be used. The oil capacity is 0.65 liter (20.3 oz.). -

Page 19: Relief Valve Cover Settings And Maintenance
6.0 Relief Valve Cover Settings and Maintenance UNIBLOC pumps may be supplied with one of the relief valve covers, shown in figure 6.0, that will minimize or eliminate problems associated with over pressurizing the pump. Relief valve covers are useful when external relief systems are not practi- cal. -
Page 20: Setting The Relief Valve Cover
6.1 Setting the Relief Valve Cover 6.1.1 Setting Relief Valve Cover: P/N 3237 Unscrew the housing (10) to reveal the adjusting mechanism. Release the lock ring (15) and turn it and the adjusting sleeve/spring adjuster (16) clockwise until they bottom out. Turn the sleeve/adjuster counterclockwise until the pressure gauge begins to drop. Lock this position with the lock ring (15). -
Page 21: Relief Valve Cover Maintenance
6.2 Relief Valve Cover Maintenance To service the valve seals the pump must not be operating, the system must be depressurized, and the pump isolated from the remainder of the system. 6.2.1 Servicing Relief Valve Cover: P/N 3237 Remove the housing (10) and mark the location of the lock ring (15). Unscrew the adjusting sleeve (16) and remove it. Remove the clamp (13) and separate the valve body and the top containing the spring. - Page 22 22 UNIBLOC-PD Operation & Service Manual: PD501-576...

Page 24: Troubleshooting
7.0 Troubleshooting PROBLEM POSSIBLE CAUSE SOLUTION 1. Motor turning in wrong 1. Reverse motor. A. No flow, but pump turns. direction 2. Fill pipe and pump with liquid. Pump does not prime. 2. Air pocket in pipe or pump. Check pipe fittings for leaks. 3. - Page 25 PROBLEM POSSIBLE CAUSE SOLUTION 1. Liquid temperature too high. 1. Lower temperature or increase D. Rotors gall, pump seizes rotor clearances. 2. Rotor clearances incorrect. 2. Adjust to factory recommended clearances. 3. Loose rotor bolts/housing studs. 3. Tighten or replace if necessary. 4.
