Hyd. Pump & Valve Repair

Examining pump repair records & mean time between failures (MTBF) is of great importance to responsible & conscientious pump users. These failure statistics often are translated into MTBF.


Not all plants are refineries, however, and different results occur elsewhere.  In chemical plants, pumps have traditionally been "thrown-away" items as chemical attack limits life.  Things have improved in recent years, but the somewhat restricted space available in "old" DIN & ASME-standardized stuffing boxes places limits on the type of seal that fits.  Unless th epump user upgrades the seal chamber, the pump only accommodates more compact & simple versions.  Without this upgrading, lifetimes in chemical installations are generally around 50% to 60% of the refinery values.

Unscheduled maintenance is often one of the most significant costs of ownership, and failures of mechanical seals & bearings are among the major causes.  Keep in mind the potential value of selecting pumps that cost more initially, but last much longer between repairs.  The MTBF of a better pump may be one to four years longer than that of its non-upgraded counterpart.  Consider that published average values of avoided pump failures range from $2600 to $12,000.  This does not include lost opportunity costs.  One pump fire occurs per 1000 failures.  Having fewer pump failures means having fewer destructive pump fires.

A typical pump failure costs, on average, $5000.  This includes costs of material, parts, labor & overhead.  Extending a pump's MTBF from 12 to 18 months would save $1667/year, which might be greater than the cost to upgrade the centrifugal pump's reliability.

Valve Repairs

We service valves from many major manufacturers & it is as important to us as servicing many other hydraulic components.  The properly functioning valve is key to any hydraulic system; so it is vital to have the experience of Material Flow LLC / TRI STATE Hydraulics to do the repair, for such an important component.

Material Flow LLC / TRI STATE Hydraulics has the capabilities to repair most hydraulic valves; including:  directional control valves, flow control valves, pressure control valves, relief valves, check valves, stack valves & main control valves found on industrial & mobile equipment.  Before the repaired valve leaves our facility, it goes through systematic procedures in accordance with OEM specifications.  Contact Us for a free quote, from our Contact Us Page.
