Unique Pump Systems UA Series — Rotary Gear Pump Range

India's Trusted Rotary Gear Pump Manufacturer — Now Serving Taloja

Taloja MIDC is one of the densest chemical and pharmaceutical manufacturing clusters near Mumbai, packed with dye, specialty chemical, and API production units that need continuous, reliable fluid transfer. Being just outside Mumbai, Taloja is practically in our backyard, and our UA Series gear pumps are already running in many of its plants. See our full Gear Pump range below.

We manufacture from our Mumbai facility just a short distance away. Below is our complete specification range, working principle and performance data, followed by what's specific to sourcing here.

How Does a Gear Pump Work?

Understanding the working principle of a rotary gear pump helps you select the right unit and maintain it effectively. Here is a step-by-step breakdown of the operating cycle:

Gear pump working principle diagram - oil flow through gear pump

1

Fluid Enters at the Inlet

As the gears rotate and unmesh on the inlet side, expanding cavities between gear teeth create a low-pressure zone. This draws fluid in from the suction port smoothly — no priming required for most viscous fluids.

2

Fluid is Trapped and Carried

The fluid is captured within the pockets formed between each gear tooth and the pump casing. As the gears rotate, this trapped volume is carried around the outer casing — from the low-pressure inlet toward the high-pressure outlet.

3

Gears Re-mesh and Build Pressure

At the outlet side, the gear teeth come back into mesh, squeezing the fluid out of the tooth pockets and forcing it through the discharge port under controlled, consistent pressure — up to 70 kg/cm² in our UA Series.

4

Constant, Pulse-Free Delivery

The result is a steady, metered flow that varies only with rotational speed — not pressure fluctuations. This predictability makes gear pumps ideal for metering, dosing, and applications where a constant delivery rate is critical to your process.

Performance Curves of Rotary Gear Pump

Performance curves help you understand how your gear pump will behave across its operating range — and are essential for verifying that the selected model will deliver the required flow at your system's discharge pressure. Unlike centrifugal pumps whose flow drops sharply with increasing pressure, a gear pump's performance curve is nearly flat — confirming constant flow across a wide pressure range.

Rotary Gear Pump Performance Curves - Pressure vs Capacity, Pressure vs Power Consumption

Performance curves showing Pressure vs Capacity & Pressure vs Power Consumption for rotary gear pump

Input B.H.P. to Pump Calculation

BHP (Rated) = Work Done / (Constant × Efficiency)

Q = [Capacity in m³/hr × Pressure in kg/cm²] / [27 (Hydraulic Constant) × Efficiency]

Relief Valve Operation

Built in pressure relief valve is provided in pumps to operate at higher than rated pressure i.e. it starts operating at 1 kg/cm² higher than rated pressure and fully opens 20% higher than rated pressure, taking maximum 30% higher power than rated power.

For model-specific and application-specific performance curves with exact data for your selected UA Series model and fluid viscosity, please contact our application engineering team.
