FAQ-Mud Pumps
Your Partner in Swattchh Bharat Abhiyan
What is an EXCEL Self Priming Mud Pump, and how does it work?
An EXCEL Self Priming Mud Pump is a heavy-duty, non-clog centrifugal pump engineered to handle dirty water, mud, sewage, and liquids containing suspended solids.
Unlike standard centrifugal pumps, it features an automatic self-priming mechanism that purges air from the suction line during startup without requiring a foot valve. Once primed, it creates a continuous suction lift to draw up heavy slurries and muddy water effortlessly.
Unlike standard centrifugal pumps, it features an automatic self-priming mechanism that purges air from the suction line during startup without requiring a foot valve. Once primed, it creates a continuous suction lift to draw up heavy slurries and muddy water effortlessly.
Does this pump require a foot valve or manual priming every time?
No. EXCEL Mud Pumps do not require a foot valve. The internal casing is designed to retain a small amount of liquid after stopping. When restarted, the pump automatically evacuates trapped air and creates a strong vacuum up to 8 meters of suction lift.

Never exceed the rated pressure of the pump or equipment under test, and ensure all connections, hoses, valves and gauges are suitable and secure.
FAQ-Internal Gear Pumps
Noice-less Operations for High Viscous Liquids at High Pressure
How does EXCEL Internal Gear Pump work?
Liquid enters the suction port as the rotor and idler teeth unmesh, creating an expanding volume that pulls fluid in. A stationary crescent seal blocks the liquid from moving backward, and the remeshing of the teeth at the discharge port forces the fluid out.
What are the main parts of the EXCEL Internal Gear Pumps?
The primary components include an internal rotor gear, an external idler gear, a crescent-shaped partition, a casing, and fluid ports.
Are EXCEL Internal Gear Pumps self-priming?
Yes, they have strong suction capabilities and can self-prime under normal operating conditions.
What fluid viscosity range EXCEL Internal Gear Pumps can handle?
They operate effectively across a broad spectrum, from thin solvents (1 cP) up to thick viscous liquid having viscosity up to 1,000 cP.
Can they handle abrasive fluids or solids?
They are designed for clean or filtered liquids. Mildly abrasive slurries can be handled if you use specialized hardened internal components, but heavy solids will cause rapid wear.
Can they run dry?
No. While they are self-priming, running them dry for extended periods destroys internal clearances, bushings, and seals due to a lack of lubrication.
What will be the life of EXCEL Internal Gear Pumps?
With correct installation and fluid compatibility, they can run for thousands of hours with minimal servicing
What are the common industry applications for EXCEL Internal Gear Pumps?
Industrial Manufacturing: Low-volume chemical injection, precise adhesive or resin dispensing, and ink circulation for printers.
Automotive & Transport: Pumping and dosing DEF/AdBlue (urea) systems, fuel cells, and small lubrication circuits.
Medical & Lab Devices: Fluid transfer and precise chemical dosing in dialysis machines and analytic instruments.
Clean Energy: Coolant circulation and fuel delivery loops in compact alternative-energy systems.
FAQ-External Gear Pumps
Oil, Diesel, Paste, Molasses or Foam - Solution For All
How does an EXCEL external gear pump work?
As the gears unmesh on the inlet side, they create an expanding volume that creates a vacuum, drawing fluid into the pump casing. The fluid is trapped between the gear teeth and the housing wall as the gears rotate around the outer perimeter. Finally, as the teeth remesh on the outlet side, the volume shrinks and forces the fluid out under pressure.
Are EXCEL external gear pumps self-priming?
Yes. Because they are positive displacement pumps, they can evacuate air from the suction line to create a vacuum and draw fluid up into the casing. However, running them completely dry for extended periods can cause severe wear due to lack of internal lubrication.
What is the maximum Flow and Pressure EXCEL External Gear Pumps can offer? What Design and Prime movers can be used with the said pumps
EXCEL External gear pump is available up to 2000 lpm and pressure up to 10 Bar Design: S6"crewed or Flanged, Port Sizes: 0.5"x0.5" to 6"x6", Gear Box Drive, Engine Drive or PTO Drive
Why is a safety pressure relief valve provided in EXCEL External Gear Pumps?
Because an external gear pump is a positive displacement pump, it delivers a fixed volume per revolution regardless of discharge pressure. If a downstream valve is closed, pressure will rapidly build up until the motor stalls, the pump housing ruptures, or piping fails. A pressure relief valve (PRV) on the discharge line or integrated into the pump cover prevents over-pressurization.
What fluids are best suited for EXCEL external gear pumps?
External gear pumps perform exceptionally well with clean, viscous liquids and high-pressure hydraulic applications:
- Ideal fluids: Hydraulic oils, lubricating oils, fuels, polymers, resins, additives, and chemical feedstocks.
- Avoid: Abrasive slurries or fluids containing solid particles, as suspended solids quickly wear down gear teeth and tight tolerances.
What are the key Advantages of EXCEL External Gear Pumps? Advantages
- High pressure capability: Compact design generates steady high discharge pressures.
- Bi-directional operation: Flow direction can be reversed by reversing motor rotation and changing Pump Casing Cover Position.
- Precise metering: Flow rate is directly proportional to rotational speed (RPM).
- Robust construction: Dual-DU Bush support allows for heavy continuous duty.
What are the limitations of EXCEL External Gear Pumps?
- No dry running: Requires fluid for internal lubrication and cooling.
- No solids allowed: Tight internal clearances mean abrasive particles cause fast degradation.
- Noise level: Can be noisy at high RPM (helical gears help reduce noise compared to straight spur gears).
