The charging pump provides back pressure to the suction and prevents mud cavitations. This is essential to the flow and life of the fluid end. Existing mud circulation pumps can be piped into the suction line if they are capable of delivering the maximum rated flow rate of the triplex pump while maintaining a pressure of 40 psi. Refer to the performance charts. NOTE: Maintain proper belt tension on charging system pump.

SECTION 3 LUBRICATION SYSTEM WARNINGS NEVER REACH INSIDE OPERATING PUMP. NEVER RUN PUMP AGAINST CLOSED VALVES (ALLL DISCHARGE VALVES CLOSED). STOP PUMP OPERATION BEFORE ATTEMPTING REPAIRS. PROPERLY LOCK-OUT OR DISCONNECT MAIN POWER SOURCE TO THE PUMP BEFORE CONDUCTING INSPECTION, MAINTENANCE OR REPAIR. COMPLETELY BLEED ALL PRESSURE FROM FLUID END BEFORE ATTEMPTING MAINTENANCE OR REPAIR. CAUTIONS ƒ

SYSTEM DESCRIPTION White Star Triplex pumps have two independent lubrication systems which provide lubricating oil to all moving parts of the pump. In addition to a pressure-fed primary system, each pump has a gravity –fed secondary system that is supplied by splash from the main gear. Model WS1600 may have an external lubrication pump driven by motor on request.

Normal oil pressure for the primary lubrication system, as indicated by the pressure gauge, is 5 to 40 psi depending upon the temperature of the oil and the operating speed of the pump. PRIMARY SYSTEM Oil in the crank case sump enters the strainer and supplies the pump through the suction line. The oil is then pumped to the gearcase manifold which contains the pressure gauge connection, a relief valve (set to open at 40 psi), and outlets to main bearings, pinion bearings and crosshead manifold.

Fig. 2-1 Oil pump location Oil pumped to the crosshead manifold is directed to each crosshead guide and onto each crosshead via grooves. The oil lubricates the upper crosshead guides and crosshead and then flows into the connecting rods, through holes in the rods and into the wrist pin bearings. The oil flows out of the wrist pin bearings through hole in the bottom of the crossheads and onto the lower crosshead guides. Oil from the crosshead manifold also feeds an oil cup on each wrist pin retainer plate. This oil passes through a hole in each wrist pin to the inner race of the wrist pin bearings and then onto the lower crosshead guides ensuring adequate lubrication of the bearings. The crosshead manifold also supplies a stream of oil to each extension rod as the rods pass through the stripper boxes. SECONDARY SYSTEM Each part lubricated by the primary system also receives oil from the gravity-fed secondary lubricating system. Two reservoirs, one above the crosshead compartment and one behind the pinion (Figure 2-2) are supplied with oil by splash from the main gear.

Fig. 2-2 Secondary lubricating system. LUBRICANT LEVEL 1. Check the lubricant level of the pump at regular intervals. The dipstick is located at the rear of the power frame (Fig 2-3).

2. If the Pump is operating, the lubricant level should be at the run mark on the dipstick. NOTE: If the lubricant level does not reach the RUN mark on the dipstick when checked, stop the pump. 3. If the pump has been stopped for at least 10 minutes, the lubricant level should be between the ADD and FULL marks on the dipstick. 4. Add lubricant if necessary.

RECOMMENDED LUBRICANTS NOTE: The recommended lubricants for the White Star mud pumps are shown in Fig. 2-6. Consult your White Star service representative before using lubricants other than those listed LUBRICANT CHANGES 1. Drain the old lubricant every 4 months or 1000 operating hours, whichever occurs first. The drain plug is located at the rear of the power frame (Figure 1-4). 2. Fill the pump with fresh lubricant. (Fig. 2-6) CAUTION CHANGE LUBRICANT IF CONTAMINATED BY DIRT, CONDENSATION OR OTHER FOREIGN SUBSTANCES.

WARNINGS NEVER REACH INSIDE OPERATING PUMP. NEVER RUN THE PUMP AGAINST CLOSED VALVES (ALLL DISCHARGE VALVES CLOSED). STOP PUMP OPERATION BEFORE ATTEMPTING REPAIRS. PROPERLY LOCK-OUT OR DISCONNECT MAIN POWER SOURCE TO THE PUMP BEFORE CONDUCTING INSPECTION, MAINTENANCE OR REPAIR. COMPLETELY BLEED ALL PRESSURE FROM FLUID END BEFORE ATTEMPTING MAINTENANCE OR REPAIR. PREVENTIVE MAINTENANCE The primary goal of a preventive maintenance program is to help the pump owner realize and control fluid circulating equipment operating costs. It is possible to control mud pump cost if life of fluid end parts can be reasonably predicted so that they can be replaced before they fail. Parts that are run to the point of failure result in unscheduled downtime, damage to other parts and excessive man hours being spent for pump repair. Besides following a program of scheduled inspection and maintenance, the owner should develop a plan for the timely replacement of expendable components based upon the average life expectancy of these components. By changing expendable parts in a group on a timely basis you can eliminate the need to continually go into the pump for routine maintenance. Changing parts or performing other schedule inspections while you are shut down for some other event that does not require pump operation (making cement, logging, etc.) further reduces pump down time. SCHEDULE MAINTENANCE DAILY (8 HOURS) 1. 2. 3. 4.
