Piusi E120/T Flange D.80 Pump 000312000

Piusi E120/T Flange D.80 (Code: 000312000) Fuel Transfer Pump

The Piusi E120/T (Part Number: 000312000) is a continuous-duty, three-phase volumetric rotary vane pump engineered for high-volume diesel transfer, day-tank bunkering, and heavy fuel conditioning skids. Built around an induction motor wound for 400V/50Hz and 460V/60Hz supplies, the E120/T delivers up to 100 L/min (26 GPM) at nominal head, with capabilities extending to 130 L/min on 60Hz marine grid systems.

The pump features an integrated internal bypass valve that protects the hydraulic circuit against overpressure during deadhead operations (e.g., automated batch valve closure or manual nozzle cut-off). Fitted with an internal flanged D.80 coupling assembly with 1″ BSP female connections, it integrates into marine engine room fuel lines, bulk fuel delivery skids, and agricultural dispensing setups requiring uninterrupted S1 continuous duty ratings.

Key Features

1. Continuous-Duty Three-Phase Motor: Powered by a dual-frequency, 3-phase induction motor (400V/50Hz – 460V/60Hz) delivering 750W to 1000W with continuous S1 duty classification without thermal throttling.
2. Internal Overpressure Bypass Protection: Integrated internal spring-loaded bypass valve permits closed-nozzle operation up to 2.8 bar differential pressure without causing rotor stall or thermal winding breakdown.
3. Rigid D.80 Flanged Interface: Direct-mount D.80 flanged port configuration with 1″ female BSP threads provides mechanical vibration isolation and quick disconnection without pipe stress.
4. Industrial IP55 Enclosure & FKM Sealing: Heavy-duty cast iron body finished with marine-grade cathodic anti-corrosion paint, paired with an IP55 terminal enclosure and high-grade Viton/FKM mechanical shaft seals resistant to hydrocarbon wear.

Frequently Asked Questions

Can the Piusi E120/T pump be run continuously without resting?

Yes. Unlike smaller 12V or 24V intermittent-duty pumps rated for 30-minute cycles, the E120/T is powered by a 400V/460V 3-phase industrial induction motor certified for S1 continuous operation, provided the fluid flow is active to carry away internal hydraulic friction heat.

What happens if the motor is connected to single-phase 230V mains?

The 000312000 model requires a 3-phase supply (400V 50Hz or 460V 60Hz). It will not operate on standard single-phase 230V household or light-workshop circuits. For single-phase 230V applications, select Piusi MPN 000326000 (E120/M).

How do I clean or inspect the vanes if flow output drops?

Isolate electrical power and lock out the supply. Close isolation valves on suction and discharge lines. Unbolt the cast iron front pump cover plate. Slide the rotor face out to inspect the acetal resin sliding vanes for edge chamfering, scoring, or debris entrapment. Reassemble with a light film of clean diesel oil on the casing perimeter; ensure the Viton seal ring is seated in its groove to prevent air ingress on suction.

Is this pump safe for pumping gasoline or ethanol blends?

No. The Piusi E120/T is not an ATEX or UL-certified explosion-proof pump. It is strictly built for non-volatile hydrocarbons with a flashpoint above 55°C (such as standard automotive diesel, marine gas oil, heating oil, and biodiesel). For volatile solvents or gasoline, an ATEX-certified pump like the Piusi EX100 series must be deployed.

What is the advantage of the Flange D.80 connection over standard threaded ports?

The D.80 flanged connection uses a flat mating face with an embedded gasket or O-ring bolted through an 80mm bolt pitch. This permits the pump to be dropped out of hard-piped marine or industrial manifold lines without unthreading or torquing rigid steel pipelines. Standard 1″ BSP female threads are also integrated inside the flange bore for threaded fittings.
