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 the transfer or dispensing of fuels such as diesel, petrol 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 working conditions involve pressure variations or intensive use.

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

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

The IRON 50 model 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 applications where speed and consistent operation are required.

On the other hand, the DIESEL BATTERY KIT represents the portable option in the range, with a pump that can be connected to a 12 V or 24 V battery, together with hoses, a filter and a nozzle. This kit has been designed for quick interventions in the field, machinery on site or vehicles without access to mains power.

All the pumps in this family share a robust construction, manufactured from fuel-resistant materials and materials resistant to mechanical wear, ensuring long service life even under adverse conditions. In addition, their compatibility with volumetric meters, line filters, safety valves and Gespasa control systems makes it possible to build complete configurations tailored to every professional requirement.

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

IRON 50 Vane Pump

The IRON 50 is a self-priming electric vane pump designed specifically for the efficient transfer of diesel in mobile and fixed applications. With a nominal flow rate of 50 litres per minute, this pump stands out for its reliability, robustness and ease of integration into professional fuel dispensing systems.

Available in 230 VAC, 110 VAC, 24 VDC and 12 VDC versions, the IRON 50 offers excellent installation versatility, adapting to both industrial environments and agricultural machinery, mobile tanks or private service stations. Its compact design incorporates a cast-iron body with anti-corrosion treatment, ensuring high resistance to oxidation and to adverse environmental conditions.

At the heart of its operation is a positive displacement system using self-adjusting vanes, which ensures a constant, pulsation-free flow, even with pressure variations or prolonged use. The pump features an internal pre-filter that prevents the entry of impurities, as well as an integrated recirculation bypass, which protects the hydraulic circuit against overpressure and enables safe, continuous operation.

Its main technical features include:

AG-90 Vane Pump

The AG-90 is a self-priming electric pump with self-adjusting vanes, developed specifically for mobile applications where a high diesel transfer flow rate is required>. Its pumping capacity, ranging between 70 and 80 litres per minute, makes it a robust, efficient and compact solution for direct refuelling from mobile tanks, lorries, tankers or agricultural machinery in the field.

The AG-90 model is available in 12 V and 24 V direct current versions, allowing direct connection to batteries in vehicles or autonomous dispensing systems. Its design incorporates a 0.37 kW electric motor, with built-in thermal protection, enabling safe starting and continuous operation without risk of overheating in intensive working cycles.

From a construction perspective, the pump features a reinforced metal structure, treated against corrosion and designed to withstand vibration, impacts and adverse conditions typical of agricultural, industrial or logistics environments. The pump body houses a recirculation bypass system, which acts as an internal safety valve to protect the system in the event of overpressure.

Its main technical features include:
• Maximum flow rate: up to 80 l/min (under optimum conditions).
• Extended-duty operation. The AG-90 can be used continuously for several hours.
