Heavy-Duty Internal & External Rotary Gear Pumps
Pulsation-Free Pumping for Viscous Oils, Resins, Bitumen & Fuel
Markserv Engineers offers robust internal and external rotary gear pumps engineered to transfer high-viscosity lubricating oils, polymers, asphalt, resins, paints, molasses, and diesel under steady, pulsation-free pressure. Precision gear meshing and thermal jacket designs ensure peak mechanical efficiency even at elevated operating temperatures.
Pulsation-Free Discharge
Continuous helical / spur gear meshing ensures constant non-turbulent laminar fluid flow, eliminating line shock in high-pressure burner or metering systems.
Thermal Heating Jackets
Steam / hot oil jacketed casings prevent temperature loss during transfer of bitumen, molten wax, resins, and heavy fuel oils up to 250°C.
Bidirectional Pumping
Reversible rotation permits quick loading and unloading of tank trucks and refinery storage vessels without modifying piping connections.
Hardened Gear Metallurgy
Nitride-hardened alloy steel and stainless steel gears with bronze / carbon bush bearings ensure exceptional wear life against viscous friction.
