T7 Series Hydraulic Vane Pump

Overview

The T7 Series is a fixed-displacement vane pump positioned for use with asynchronous or synchronous motors controlled by frequency inverters. Unlike conventional fixed-displacement pumps that rely on valve throttling for speed control, the T7 Series allows pump speed to vary in real time according to demand, eliminating wasted energy at the source.

The series offers single and double pump configurations. Displacement ranges from 5.8 to 137.5 cm³/rev, with operating pressure up to 320 bar depending on size, and maximum speed up to 3000 RPM (select small-displacement variants reach 3600 RPM). Weight ranges from approximately 9.5 to 26 kg, with a compact design that facilitates drop-in replacement on existing equipment.

Key Features & Advantages

1. Significant Energy Savings, Lower Total System Cost

The T7 Series’ most compelling advantage lies in the efficiency gains enabled by variable speed drives. According to Parker, electric motor energy consumption can be reduced by up to 70% when paired with inverter-controlled variable speed systems. Because heat generation is lower, hydraulic equipment cooling requirements are substantially reduced—or eliminated entirely. System-level benefits cascade: smaller reservoirs, fewer valves, more compact power units, and extended component life.

2. Pressure-Balanced Design for Longer Service Life

The T7 Series employs a fully pressure-balanced design that equalizes hydraulic forces between rotor and cam ring across the full operating range, reducing wear and efficiency degradation. Combined with double-lip vanes, the design maintains tight vane-to-cam contact while offering greater tolerance to particulate contamination in the fluid, lowering the risk of performance loss due to fluid degradation.

3. Low Noise Through Denison Vane Technology

Noise is a common complaint in hydraulic power units. The T7 Series leverages Denison vane technology to maintain low noise levels across the entire operating range and throughout the pump’s service life. For injection molding shops, die casting cells, and other noise-sensitive environments, this directly improves operator experience and supports compliance.

4. Wide Speed Range with Stable Output

The T7 Series is optimized for speed adaptability in variable drive applications. Under inverter control, the pump operates efficiently across a broad speed range, with flow varying precisely with speed and high repeatability. This means low-speed conditions—such as pressure holding or slow mold closing—do not cause the oil temperature spikes associated with throttling losses in conventional fixed-displacement systems.

5. Compact Design and Flexible Combinations

The T7 Series offers multiple displacements within the same mounting size, reducing the need for equipment manufacturers to redesign interfaces when flow requirements change. Individual pumping cartridges can be combined into double or even multiple pumps, enabling composite circuits with high-pressure/low-flow and low-pressure/high-flow sections for high power density requirements.
