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.
