Why is my Weir SPM TWS600S experiencing low discharge pressure and running roughly?

  Michael ParkerAug 1, 2025
  Low discharge pressure and rough running in your Weir Water Pump can stem from several causes: worn or damaged valve assemblies; insufficient supercharge flow or pressure; air, gas, or vapor in the fluid being pumped; an improperly charged or ineffective suction pulsation dampener; two or more plunger pumps being supercharged by a common charge pump and getting “in phase” with each other; or the pump not being primed properly.

What causes abnormally high lube oil temperature in a Weir SPM TWS600S?

  James OliverAug 5, 2025
  Abnormally high lube oil temperature in your Weir Water Pump might be due to several factors: extremely warm ambient temperature, dangerously low oil viscosity, or the use of an incorrect grade of gear oil. Other potential causes include gear oil contaminated with water, trash, or air bubbles; continuous operation of the plunger pump for an extended period near its maximum horsepower or torque rating; a malfunctioning heat exchanger or oil cooler; an erroneous gauge reading; internal power end damage or wear; or a thermostatic valve malfunction.

Why is the lube oil pressure abnormally low in my Weir SPM TWS600S?
- J
  Joseph WilsonAug 9, 2025
  Abnormally low lube oil pressure in your Weir Water Pump, with a normal to low vacuum reading, can be attributed to: a leak in the lube pump suction piping allowing air to enter; a worn or damaged lube pump; a leak in the lube pump pressure piping; low oil level in the reservoir; a clogged oil filter element; a faulty lube system relief valve; extremely hot lube oil temperature causing dangerously low oil viscosity; or an erroneous gauge reading.

Why is there a fluid leak from the plunger or packing of my Weir Water Pump?
- D
  David FosterAug 13, 2025
  A fluid leak from the plunger and/or packing of your Weir Water Pump could be due to several reasons: the packing nut not being tightened properly; worn or damaged packing; the packing being installed improperly; the mating seal surface not being cleaned properly before packing installation; a damaged or corroded mating seal surface; the fluid being pumped being incompatible with the style packing being used; or a damaged or improperly installed wiper ring.

Why is there abnormally high vacuum at the lube pump suction inlet of my Weir SPM TWS600S?
- S
  Steven WadeAug 18, 2025
  Abnormally high vacuum at the power end lube pump suction inlet of your Weir Water Pump could be due to: extremely cold ambient temperature causing dangerously high oil viscosity; a clogged lube system suction strainer; a kinked or collapsed lube system suction hose; a clogged oil reservoir breather; an erroneous gauge reading; or a closed tank valve.
