Cat Pumps Plunger pump 2SF35

Clean Filters: Inspect and clean inlet filters on a regular schedule to avoid flow restriction. Use adequate mesh size for liquid and pump specifications.

Inadequate inlet conditions can cause serious malfunctions in the best designed pump. Surprisingly, the simplest of things can cause the most severe problems or go unnoticed to the unfamiliar or untrained eye. REVIEW THIS CHECK-LIST BEFORE OPERATION OF ANY SYSTEM. Remember, no two systems are alike, so there can be no ONE best way to set-up a system. All factors must be carefully considered.

INLET SUPPLY should exceed the maximum flow being delivered by the pump to assure proper performance.

❏ Open inlet shut-off valve and turn on water supply to avoid starving the pump. DO NOT RUN PUMP DRY.

❏ Temperatures above 130°F are permissible. Add 1/2 PSI inlet pressure per each degree F over 130°F. Elastomer or RPM changes may be required.

See Tech Bulletin 002 or call CAT PUMPS for recommendations.

❏ Avoid closed loop systems especially with high temperature or ultra-high pressure. Conditions vary with regulating/unloader valve.

❏ Higher temperature liquids tend to vaporize and require positive heads.

Fill crankcase with special CAT PUMP oil per pump specifications [2SF, 2SFX: prior 3/03-11.83 oz., after 3/03-10.15 oz., 4SF: 23.66 oz.]. DO NOT RUN PUMP WITHOUT OIL IN CRANKCASE.

Change initial fill after 50 hours running period. Thereafter, change oil every 3 months or 500 hour intervals.

* If other than CAT PUMPS special multi-viscosity ISO68 oil is used, change cycle should be every 300 hours.

Each system’s maintenance cycle will be exclusive. If system performance decreases, check immediately. If no wear at 1500 hours, check again at 2000 hours and each 500 hours until wear is observed. Valves typically require changing every other seal change. Duty cycle, temperature, quality of pumped liquid and inlet feed conditions all effect the life of pump wear parts and service cycle.

Remember to service the regulator/unloader at each seal servicing and check all system accessories and connections before resuming operation.
