Vane pumps

Gespasa vane pumps: stable flow and professional performance in every transfer

The vane pumps developed by Gespasa provide a reliable, durable and highly efficient solution for fuel transfer or dispensing of fuels such as diesel, gasoline and biodiesel. Based on the positive displacement principle using an eccentric rotor with self-adjusting vanes, these pumps ensure a constant flow rate, even when operating conditions involve pressure variations or intensive use.

One of the key technical advantages of this technology is its ability to automatically compensate for internal wear without loss of performance, which significantly reduces maintenance needs and extends the service life of the equipment. Thanks to this design, the transfer is carried out without pulsation, which protects downstream components and enables more precise control of the transferred volume.

The range includes models designed for both fixed installations and mobile or standalone applications, covering a wide variety of use scenarios: from agricultural operations to transport fleets, as well as workshops, private service stations or temporary refuelling points.

The IRON 50 is a compact self-priming pump, ideal for fixed transfer systems, standing out for its mechanical reliability and ease of integration. The AG 90 and AG 100 models offer higher flow capacity and electrical versatility, making them suitable for more demanding environments where speed and continuous operation are required.

Meanwhile, the DIESEL BATTERY KIT is the portable option in the range, with a pump that can be connected to a 12 V or 24 V battery, along with hoses, a filter and a nozzle. This kit is designed for quick interventions in the field, construction-site machinery or vehicles with no access to mains power.

All pumps in this family share a robust construction, manufactured with fuel-resistant materials and built for mechanical wear resistance, ensuring long service life even under adverse conditions. In addition, their compatibility with positive displacement flow meters, in-line filters, safety valves and Gespasa control systems enables complete configurations tailored to each professional requirement.

Ease of installation, low energy consumption and operational reliability make Gespasa vane pumps a market benchmark for technical fuel transfer. Adaptable, precise and durable, these pumps provide an ideal balance between simple technology and consistent performance.
