How to Reduce Slurry Pump Maintenance Costs

Slurry pump maintenance costs can rise when wear is found too late or the wrong replacement parts are selected.Monitor the PumpCheck flow, discharge pressure, motor current and vibration during normal...

Why Does a Pneumatic Slurry Knife Gate Valve Stop Closing?

A knife gate valve that stops short of fully closing is often blamed on the pneumatic actuator. In a slurry line, that may only be the symptom.Before changing the actuator, check the gate and seat. Ha...

Throatbush for Slurry Pumps: Wear and Replacement Guide

A throatbush is a stationary wet-end part located near the impeller. It helps guide slurry into the pump and maintain the correct internal clearance.Signs of WearA worn throatbush may cause:Reduced fl...

Line Pressure Is Not Enough to Size a Pneumatic Knife Gate Valve

A valve enquiry may state only two details: DN300 and 10 bar. That sounds specific, but it is still not enough to select a pneumatic knife gate valve.The actuator must overcome the force created by di...

A Hot Slurry Pump Bearing Assembly Is a Warning, Not a Diagnosis

On a mine site, a rising bearing temperature often leads to a quick decision: replace the bearing assembly. That is not always the right first move.The heat may come from contaminated or incorrectly a...

The Slurry Pump Runs, but Nothing Reaches the Discharge

A slurry pump stops normally at the end of a shift. The next morning, the motor starts and the shaft turns, but no slurry reaches the discharge line.This does not immediately mean that the impeller is...

Sand Pump Output: More Water Does Not Mean More Sand

A strong discharge can make a sand pump look productive. But the water leaving the pipe is only part of the story. What matters in sand mining is how much sand arrives with it.Consider a simple exampl...

High Head Slurry Pumps: When the Pipeline Gets Longer

A tailings discharge point moves farther from the plant. Extra pipe is installed, the pump restarts, and throughput falls—even though the motor is running at the same speed.The pump may still be in go...

Why Is the Motor Above the Sump on a Vertical Slurry Pump?

In a typical vertical slurry pump, the wet end operates inside the sump while the motor and bearing assembly remain above the liquid. This layout is especially useful when the slurry contains abrasive...
