Swedish sunfab plunger pump SCP-084R-V-I44-W40

II Introduction to Sunfab plunger pump SCP-084R-V-I44-W40-Z1M-300

The Sunfab piston pump SCP-084R-V-I44-W40-Z1M-300 is an axial piston pump with a slanted disc design, mainly used in mobile hydraulic systems such as construction machinery, agricultural equipment, sanitation vehicles, etc. The following is an objective technical introduction to this model, organized based on Sunfab naming conventions and product catalogs:

1. Model Analysis (SCP-084R-V-I44-W40-Z1M-300)

The SCP series models of Sunfab adopt modular coding method, and the meanings of each segment are as follows:

SCP: Swash Plate Axial Piston Pump

084: Displacement code, indicating a geometric displacement of approximately 84 cm ³/rev (specific values need to be checked in the technical table, usually 83.9 or 84.2 cm ³/rev)

R: Right rotation (clockwise rotation, viewed from the shaft end)

V: SAE B spline shaft (typical 13T 16/32 DP)

I44: Integrated internal charge pump with a displacement of approximately 1.5-2.0 cm ³/rev, used for refueling closed systems

W40: The oil port is a SAE Code 61 flange (3/4 'SAE, pressure port), and the suction/discharge port is threaded or flanged (depending on the configuration)

Z1M: equipped with integrated flushing/oil replenishment overflow valve and one-way valve (typical for closed systems), M represents a specific pressure setting (such as oil replenishment pressure of 14-20 bar)

300: The maximum working pressure is 300 bar (continuous working pressure), and the peak pressure may be higher (such as 350 bar, short-term)

2. Main technical characteristics

Type: Slant type, Variable/Quantitative (SCP series is a quantitative pump)

Displacement: Approximately 84 cm ³/rev

limitWorking pressure: 300 bar (30 MPa)

Speed range: typically 600-2800 rpm (limited by power and oil viscosity)

Drive shaft: SAE B spline (13T), compliant with ANSI B92.1

Oil port connection:

High pressure port: SAE Code 61 (3/4 ') flange

Drain port: typically 1/4 'NPT or SAE thread

Oil replenishment system: Built in gear replenishment pump (I44), suitable for closed circuits (such as HST drive systems)

Control attachment: Z1M type integrated valve group includes:

Oil replenishment overflow valve (set at approximately 14-20 bar)

Two low-pressure check valves (for replenishing oil on the low-pressure side of the system)

Optional flushing valve circuit (supported by some Z1M versions)

Rotation direction: right-handed (R)

Material: The shell is made of high-strength cast iron, the shaft is made of alloy steel, and the distribution plate is made of copper alloy

Efficiency: Volume efficiency ≥ 95% (under rated operating conditions)

Applicable oil: Mineral hydraulic oil (ISO VG 32-68), meeting the cleanliness requirements of ISO 4406

3. Typical applications

Closed Loop Systems:

Construction machinery walking drive (such as skid steer loaders, excavator loaders)

Agricultural machinery (harvesters, sprayers)

Municipal vehicles (road sweepers, aerial work platforms)

Should be used in conjunction with bidirectional variable motors (such as Sunfab SCM series)

Suitable for hydraulic systems of mobile devices with compact space and high power density

4. Installation and maintenance precautions

Before installation, ensure that the drive shaft is well aligned (allowing radial runout ≤ 0.05 mm)

Before the first start-up, the pump should be filled through the oil replenishment port to avoid dry operation

The drain pipe must be directly returned to the oil tank (not combined with the main return oil), with a back pressure of ≤ 2 bar

Suggest using oil suction filters (≤ 100 μ m) and high-pressure filters (≤ 10 μ m)

III Introduction to plunger pump

A plunger pump is a type of positive displacement hydraulic pump that uses the reciprocating motion of the plunger in the cylinder to achieve the suction and discharge of hydraulic oil. It has the characteristics of high pressure, high efficiency, and stable flow, and is widely used in industrial and mobile hydraulic systems.

main types
Axial piston pump: The plunger axis is parallel to the transmission shaft, with a compact structure, commonly used in medium and high pressure systems (such as the Sunfab SCP series).
Radial piston pump: The pistons are arranged radially, suitable for ultra-high pressure or special working conditions, but with a large volume.

Core Features
High pressure capability: The working pressure can usually reach 200-400 bar, with some models even higher;
High volumetric efficiency: small internal leakage, high energy conversion efficiency;
Variable/quantitative options: Variable pump can adjust displacement to meet different load requirements;
Wide displacement range: from a few cm ³/rev to hundreds of cm ³/rev, meeting the needs of small equipment to heavy machinery;
Reliable Material: Key components are made of high-strength alloy steel and hardened to ensure durability.

Typical application scenarios
Construction machinery: excavators, aerial work platforms, cranes;
Agricultural and forestry equipment: combine harvesters, wood processors;
Industrial equipment: injection molding machines, press machines, testing benches;
Special vehicles: garbage trucks, fire trucks, airport ground handling equipment;
Renewable energy: wind power pitch and yaw systems.

4、 Introduction to Xierko

SilkRoad24 (Shanghai) Co., Ltd.) originated from Silkroad 24 GmbH, a German company established in Braunschweig, Germany in 1999. "Silkroad" is also the Chinese transliteration of "Silk". The founder, CHEN GANG (who holds a master's degree in engineering from Tongji University and Darmstadt University in Germany), has worked for Siemens Automotive and Volkswagen Wolfsburg headquarters in Germany for nearly 12 years and is familiar with the secrets of German industrial automation, large-scale production, and logistics.

In 2005, Xier Ke Business Consulting (Shanghai) Co., Ltd. was established in Shanghai. As the Chinese agent of several European companies such as Ahlborn, Aircom, Beck, and Honsberg from Germany, Xier Ke has accumulated valuable experience in serving the Chinese industrial automation industry and established a service philosophy based on customer needs. In 2006, in response to the demand of Chinese customers for German industrial spare parts, Xieke Trading (Shanghai) Co., Ltd. was established in Pudong. Taking advantage of the company's headquarters in Germany and years of trade with German suppliers, Xieke Company began to act as an agent for Chinese customers to purchase spare parts for various industries, mainly industrial automation and instrumentation. In order to meet the needs of customers for small amount orders, we have made innovations such as consolidated orders at the source in Germany, centralized agent procurement, warehousing, and centralized customs clearance outside the European Union, which greatly reduces the additional costs for Chinese customers in European spare parts procurement except for the price of goods.
