Tandem Gear Pumps (Double / Multi-Stage)
Two or three pump stages mounted on a shared drive shaft with isolated suction and delivery ports. Powers dual circuits, hi-lo rapid-traverse press circuits, or secondary auxiliary services from a single motor.
Explore SpecificationsWhat is an Industrial Hydraulic Gear Pump?
A hydraulic gear pump is a positive displacement fluid power generator that uses the mechanical engagement of two precision-cut rotating gears to pump incompressible fluid under pressure. One gear is driven directly by the prime mover shaft (the driver gear), while the second gear meshes with it (the driven or idler gear).
As the gear teeth unmesh on the suction side, they create expanding internal volume and a localized low-pressure zone that draws hydraulic oil from the reservoir through a submerged Suction Strainer. The oil is trapped within the individual tooth cavities and carried around the outer casing perimeter to the discharge port. When the teeth mesh back together on the outlet side, the fluid is displaced positively into the circuit—driving Hydraulic Cylinders and valve circuits via Manifold Blocks.
As a specialized hydraulic gear pump manufacturer in Ahmedabad, Honeywell Hydraulics engineers pumps specifically suited for continuous heavy industrial cycles. We incorporate pressure-balanced bronze wear plates that automatically minimize gear tip and side clearances as pressure rises, maintaining high volumetric efficiency (>90%) without thermal binding.
Engineering Precision & Performance
Why mechanical engineers and machine builders specify Honeywell Hydraulics external gear pumps.
High Volumetric Efficiency
Precision-machined gear tooth profiles with balanced pressure plates ensure volumetric efficiency exceeding 90% across continuous industrial operating cycles.
Rigid Extruded Body Construction
High-tensile aluminum alloy or heavy-duty cast iron body options engineered to resist cyclic pressure fatigue and hydraulic shock loads up to 280 Bar.
Standard Industrial Frame Sizes
Available across standardized Group 1, Group 2, and Group 3 frame architectures with displacements ranging from 1.2 cc/rev up to 90 cc/rev for seamless retrofit.
Low Operating Noise & Pulsation
Optimized helical or low-pulsation spur gear tooth geometries provide smooth, uniform fluid displacement with reduced acoustic decibel levels in indoor factory environments.
100% Pre-Dispatch Flow & Pressure Bench Testing
Every gear pump is dyno-tested on our automated hydraulic test bench to verify flow rate, pressure holding, volumetric efficiency, and shaft seal integrity before shipping.

How to Select the Right Hydraulic Gear Pump
When selecting an industrial gear pump, hydraulic design engineers must evaluate three primary operating factors:
Required Flow (LPM)
Calculated from cylinder bore, stroke length, and required travel speed in seconds. Sized using: LPM = [Displacement (cc) × RPM × Efficiency] ÷ 1000.
Working Pressure (Bar)
Determine continuous working pressure vs peak transient relief valve pressure. Group 2 aluminum pumps handle up to 210–250 Bar, while cast iron models exceed 280 Bar.
Single vs Tandem Pump
If your machine requires high flow for approach and high pressure for clamping, select a Tandem Gear Pump to reduce motor kilowatt size by up to 50%.
