Serie tipo DT-STP

The pump comprises two principal parts: the motor with its aspiration mechanism, which is completely immersed and forms the flameproof enclosure, and the discharge head. The two are connected by concentric pipes — the inner pipe carries the power supply cable, the outer pipe carries the pumped liquid.

An electric motor-driven centrifugal pump is connected to a manifold assembly by a coaxial column pipe assembly that transfers fuel from the pump to the manifold and electrically connects the motor to the incoming power. The centrifugal motor is submerged in the liquid contained in the storage tank, supplying motor fuel to one or more remote control-type dispensing locations.

STP pump for petrol stations and fuel dispensers

In the fuel retail trade the submersible turbine pump is normally called an STP pump. It stands at the bottom of the underground storage tank and pushes fuel up to the petrol pumps on the forecourt — the in-tank alternative to a suction pump mounted on the dispenser. Because the motor runs fully submerged in the fuel, an STP pump needs no separate priming and can feed several dispensers at once.

An STP petrol pump is sized by the number of dispensers it feeds and by the length of the pipe run.

The Type DT-STP is our own submersible turbine pump ATEX certified for Zone 0 and Zone 1, which makes it a practical submersible pump for fuel station and small oil depot service. It is also known as a fuel dispenser pump, an in-tank fuel pump, an underground tank pump, or simply an STP fuel pump.

Guía de selección

Dimensionar una bomba sumergible STP para la estación

Qué tiene que mover la bomba, y qué enviarnos para que podamos responder con un modelo y un montaje de tubería en lugar de una referencia de catálogo.

Una bomba sumergible de turbina STP va en el fondo del depósito y empuja el combustible hasta la estación. El oficio llama a esa misma unidad bomba STP o bomba de combustible STP; en una especificación aparece como equipo de combustible STP, bomba de gasolina STP, bomba de surtidor de combustible, bomba sumergible de surtidor de combustible o bomba de combustible intradepósito. Como fabricante de bombas sumergibles de turbina fabricamos una sola familia para todos esos nombres — la serie Tipo DT-STP, catalogada como bomba sumergible STP y conocida en su nombre completo como bomba sumergible de turbina STP.

A submersible pump for gas station forecourts is the same machine as a gas station submersible pump in a truck stop or a petrol station submersible pump at a retail site; the duty does not change with the name. The same unit works as a submersible pump for fuel station islands, a storage tank pump in a small fuel depot, a submersible pump for oil depot loading bays, and an underground tank pump wherever the tank is buried. Read an underground storage tank pump or submersible pump for underground tank specification anywhere in the market and it describes this duty: tank bottom to dispenser inlet, at a petrol station, across a petrol pump island.

Because the motor runs immersed, one submersible fuel pump body covers diesel, kerosene and gasoline. That is a diesel submersible pump for depot and truck lanes, a gasoline submersible pump for car forecourts and a kerosene submersible pump for heating-oil outlets, with ethanol and methanol gasoline blends approved on the same build. A fuel submersible pump bought today therefore does not have to be replaced when the site changes blend.

Motor size follows the number of dispensers and the length of the run, not the size of the tank. A single-island site is normally served by a 0.75 HP submersible pump, a 1.5 HP submersible pump or a 2 HP submersible pump; a busy multi-island forecourt takes a 3 HP submersible pump or a 5 HP submersible pump. At the top of the range a 5 HP submersible turbine pump is a 1000 L/min submersible pump — which is what makes this a high flow submersible pump and a high capacity submersible pump rather than a domestic unit. The hydraulic end is a centrifugal submersible pump; the submersible pump motor behind it is supplied as a single phase submersible pump build at 220 V or a three phase submersible pump build at 380 V.

Every model is an ATEX submersible pump. The motor and its aspiration mechanism form the flameproof enclosure, which makes it a flameproof submersible pump approved as a zone 0 submersible pump for the tank interior — a submersible turbine pump ATEX installation covered by type examination certificate IEP 26 ATEX 1836X, with EAC approval for the Eurasian market. The motor housing is IP68, so the same IP68 submersible motor seal that keeps fuel out of the winding also keeps the enclosure flameproof.

Above the tank, the discharge head carries the manifold, the lifting eye, the electrical connector and the line check valve, and the motor hangs below it on a column pipe. Two pipe builds are offered: galvanized steel, or a telescopic pipe that takes up burial-depth tolerance on site without cutting pipe. Tell us the tank depth, the number of dispensers and the litres per minute you need at the busiest nozzle, and we will size the pump and the column pipe together.

Replacement Guide

Red Jacket and Blue Jacket STP Replacement

The Type DT-STP is made in China as a drop-in replacement for Red Jacket and Blue Jacket submersible turbine pumps — a Red Jacket STP replacement or a Blue Jacket replacement on an existing forecourt.

Most Red Jacket submersible pump and Blue Jacket STP sites are not new builds. The station was commissioned years ago, the pump has reached the end of its service life, and what the owner needs is a unit that goes back into the same well, the same pipework and the same electrical supply.

A Red Jacket STP replacement order is confirmed against the site, not against a photograph. Send us the model you are taking out, the tank depth, the number of dispensers it feeds and the litres per minute you need at the busiest nozzle. As a China submersible pump manufacturer and an STP pump manufacturer in China, we answer with the DT-STP model, the column pipe build and the pipe length, and we confirm the match before the order is placed.

We are a submersible turbine pump manufacturer in China, and every DT-STP is built and tested as one assembly: motor, hydraulic end, discharge head and column pipe.

China factory supply

Submersible turbine pump supply from China

How an STP order is quoted direct from the factory, and what a replacement order has to match.

As a China submersible turbine pump manufacturer we build the pump end, the motor and the column in one workshop, so a China submersible turbine pump order leaves together with its spares. A China STP manufacturer bidding against an existing drawing is doing the same job our team does: we are a China STP supplier from 0.75 hp to 5 hp, and a China STP pump source for 1.5 inch to 3 inch risers.

Export footprint by line: submersible turbine pump China, submersible turbine pump manufacturer China, STP manufacturer China and Red Jacket China all leave from the same Wenzhou gate. A replacement is a drop-in part, so we quote a Red Jacket replacement rather than a copy: send the tank size, the discharge head and the riser diameter and we will confirm which Red Jacket replacement China unit, or which China Red Jacket replacement part, matches. A Red Jacket compatible assembly is not automatically a Red Jacket STP replacement, so a Red Jacket STP replacement China order starts with the tag photograph, and a China Red Jacket STP replacement is quoted only against a model we can verify.

We treat an STP pump replacement as a commissioning job rather than a parts-counter sale. The intake screen filter, the packer manifold, the line check valve and the PLLD are matched to the tank already on site, the discharge head is re-set, and the capacitor and relay are supplied to the motor actually fitted.
