100 cc double-acting oil extraction pump made of brass

The professional solution for changing oil in gensets, generators and industrial engines

The 100 cc double-acting oil extraction pump (code 1009016) is an engine accessory designed by AB Trasmissioni to meet the needs of those working in intensive maintenance situations, and cannot afford to compromise reliability, durability and operational accuracy.

Made with a solid brass body, this hand pump sets the standard for oil change on generator sets, generators, engine-driven compressors and engines of all types — including marine applications where corrosion resistance is a non-negotiable requirement.

Double acting pump

Technical Specifications

Oil change pump: technical description

Corpo in ottone: perché fa la differenza

The chosen pump build material is not a minor detail: it is the core of the entire value proposition. Brass — a copper and zinc alloy — has always been a favored material in hydraulic and mechanical systems for a number of precise technical reasons:

• Corrosion resistance: brass does not oxidize in the presence of oil, fuels or atmospheric humidity. In marine environments, where brackish air and seawater systematically attack metal components, brass retains its structural and functional characteristics over time, unlike untreated iron or steel.
• Mechanical strength: the brass body guarantees resistance to the stresses of repeated use, pressures created by the double-acting mechanism and wear from maintenance cycles.
• Machinability and dimensional accuracy: brass allows very tight machining tolerances, which are essential to ensure hydraulic sealing in the system and suction efficiency.
• Chemical inertia in engine oils: unlike certain polymers or ferrous metals, brass does not react with lubricating oils, even synthetic or high-viscosity ones, so it retains the properties of the extracted fluid unaltered.

Double acting: maximum efficiency for every stroke

The double-acting principle is the technical feature that distinguishes this pump from single-acting solutions on the market. In a single-acting pump, fluid is only sucked during the piston return stroke.

In a double-acting pump, instead, suction takes place in both directions of travel: during both stem thrust and retraction.

This translates into real, measurable benefits:

• Almost double the extraction speed for the same number of manual cycles by the operator.
• Less operator fatigue due to the work being spread over both strokes.
• More continuous, smooth flow of the extracted oil, with less risk of clogging or fluid return.
• Suction volume of about 100 cc for each full stroke of 185mm, which makes it easy to estimate operating times, even for large tanks

Versatile fittings: universal compatibility

The pump is designed to adapt to different system configurations without requiring additional pipe fittings:

• Hose adapter for Ø 12.5 mm hoses: the standard configuration for connecting hoses, ideal to reach drain plugs in inaccessible places
• M14x1.5 mm female threaded fitting: available by unscrewing the hose adapter insert to allow direct connection to standard male threaded fittings
• M14x1.5 mm male threaded fitting: at the opposite end for connection to female fittings or directly compatible threaded drain plugs

The M14x1.5 metric thread is one of the most popular sizes in the industrial and marine engine sector, which makes this pump compatible with the vast majority of applications without the need for adapters.

Pump mountings: easy installation

The pump is equipped with a bracket so it is easy to attach to any machine with which it must work.

Dimensions and technical reference data

Benefits for the marine sector: brass is unparalleled at sea

The marine sector imposes extraordinarily strict requirements on maintenance equipment. Marine oil extraction pumps are faced with conditions that put a strain on any material in the long term.

The marine environment: a relentless corrosive agent

Salt water contains high concentrations of chlorides — 35 grams per liter on average — which dramatically accelerate galvanic and electrochemical corrosion processes. Untreated ferrous metals, as well as many aluminum alloys, undergo significant structural degradation in a few months of on-board exposure.

Because of its copper and zinc composition, brass is much more resistant to this environment. A surface layer of copper oxide (coating) forms and creates a natural barrier that further slows down chloride attack, without compromising component functionality.

Specific marine applications

This oil extraction pump made of brass is applied directly in:

Inboard and outboard engines
Changing the oil on boats with inboard engines often requires suction from above, through the dipstick tube, because the drain plug is not accessible with the boat in the water. The double-acting pump with a Ø 12.5 mm hose is ideal for this type of operation because it ensures fast extraction with no leaks.

Marine gensets
Medium and large pleasure boats, super yachts and work vessels are equipped with auxiliary generators that require scheduled oil maintenance. The brass pump withstands the engine compartment environment — wet, hot, with salt aerosols — better than any solution based on plastic or ferrous metals.

Hybrid propulsion systems and auxiliary engines
In professional boating and advanced recreation, proper maintenance on auxiliary propulsion systems requires equipment of certifiable quality. Brass is a material that shipbuilders adopt as standard, precisely because its durability is proven and certifiable.

Bilge pumps and on-board compressors
On-board ancillary systems — engine-driven compressors, electric winches, hoists — also have lubricating circuits that need maintenance. The versatility of the fittings on this pump makes it usable on a variety of engines and systems, reducing the amount of equipment to be kept on board.

Industrial application sectors: where this pump works every day

Gensets

Gensets are among the most popular applications for this type of pump. Industrial gensets — used in construction sites, hospitals, data centers, production plants — operate in heavy duty cycles that require frequent, precise oil changes. The double-acting pump can change oil without having to take the unit out of service for long periods, reducing downtime and simplifying preventive maintenance procedures.

Compatibility with the M14x1.5 thread covers most European and Asian diesel genset engines, making this pump a universal piece of equipment in the maintenance technician's kit.

Engine-driven compressors

Engine-driven compressors with internal combustion engines — used in construction, mining, agriculture, and workshops — require regular oil changes on both the engine and, in some models, the compressor unit. The robust construction of the brass pump and its ease of operation also make it suitable for use on site, in difficult environmental conditions, and with operators who are not necessarily specialized.

Industrial and backup generators

In emergency generator systems installed in critical facilities, preventive maintenance is a procedural obligation, not a choice. The availability of reliable, precise and durable oil extraction equipment is an integral part of any certified maintenance plan. With its brass construction and double-acting mechanism, the 1009016 pump fits perfectly into this operating context.

Static and mobile industrial engines

Any internal combustion engine — whether a forklift engine, engine-driven pump for irrigation, tractor or static engine for industrial use — requires oil change cycles, which can be optimized with this pump. The portability of the equipment (total length 333.5mm, low weight) makes it easy to use even in environments with limited maneuvering space.

Ergonomics and ease of use: maintenance should not be a problem

Ease of operation is one of the guiding principles of the project. The pump does not require electrical power, does not require calibration and has no quick wear components requiring frequent replacement.

The manual operating mechanism with 185 mm stem stroke is sized for a secure grip even with work gloves. The absence of valves or complex mechanisms minimizes the chances of failure and simplifies any cleaning or periodic inspection procedures.

The threaded hose adapter insert — which conceals the M14x1.5 female threaded fitting — is an example of design for functionality: it takes just a few seconds to change from a hose configuration to one with a direct threaded connection to adapt the equipment for a specific need without additional tools.

Conclusion: a simple but essential piece of equipment

The 100 cc double-acting oil extraction pump made of brass (code 1009016) is the right answer for anyone looking for professional, durable and versatile maintenance equipment.

The double-acting mechanism ensures superior performance compared to single-acting solutions; the brass body ensures long-term durability, even in the most aggressive conditions, such as the marine environment; compatibility with M14x1.5 threads and Ø 12.5 mm hoses makes it immediately usable on a wide range of industrial and marine engines.

For gensets, generators, engine-driven compressors and work engines: this pump is the equipment that should never be missing from the maintenance kit for anyone working in the field and, why not, for anyone who wants to be autonomous with effective equipment for immediate use.
