AIRIPA OSV Series Oil-Injected Screw Vacuum Pump

1. Product Overview

The AIRIPA OSV Series Oil-Injected Screw Vacuum Pump is a range of industrial vacuum pumping units designed for equipment manufacturers and industrial users requiring different levels of pumping capacity. Covering 11 models from OSV590 to OSV5400, the series offers nominal pumping speeds from 588 to 5,400 m³/h and motor power ratings from 7.5 to 90 kW, providing multiple options for industrial vacuum system integration.

The OSV series employs oil-injected screw vacuum technology, in which oil supports sealing, lubrication, and heat removal during the pumping process. This design differs from an oil-free dry screw vacuum pump and requires appropriate oil management and maintenance.

The series includes models with specified ultimate pressures of 30 Pa and 60–80 Pa, depending on the model. Inlet connections range from DN80 to DN250, allowing buyers to evaluate different pumping capacities and piping configurations within a single product family.

AIRIPA manufactures industrial vacuum equipment with in-house production, assembly, and factory testing capabilities. We also support OEM, ODM, and private labeling discussions for industrial equipment manufacturers, distributors, and vacuum system integrators.

2. Key Features & Benefits

Wide Pumping Capacity: 588–5,400 m³/h

The OSV series covers a broad nominal pumping speed range, allowing buyers to compare models for different gas loads and vacuum system capacities. The 11-model lineup supports selection without changing to a completely different product family.

Oil-Injected Screw Vacuum Technology

The oil-injected screw pumping mechanism uses oil to assist with internal sealing, lubrication, and heat transfer. These functions support the compression process and distinguish the OSV series from dry, oil-free screw vacuum pump designs.

Multiple Motor Power Options

Motor ratings range from 7.5 kW for the OSV590 to 90 kW for the OSV5400. This range gives equipment designers clearly defined electrical specifications for preliminary system planning. Actual energy consumption should be evaluated using operating conditions and performance data.

Model-Specific Ultimate Pressure

The OSV590, OSV690, and OSV880 are specified at 30 Pa ultimate pressure. The remaining models are listed at 60–80 Pa in the supplied technical data. Buyers should consider both the required working pressure and the pump's pumping speed at that pressure when selecting a model.

Industrial Inlet and Exhaust Connections

Depending on the model, inlet sizes range from DN80 to DN250, while exhaust sizes range from DN65 to DN200. These connection options help system engineers plan compatible vacuum piping and equipment layouts.

Integrated Industrial Equipment Configuration

The OSV series is supplied in industrial equipment configurations with specified overall dimensions and weights. These details support early-stage planning for installation space, lifting arrangements, and equipment integration.

Factory-Direct Manufacturing and Customization Support

AIRIPA provides direct communication with its manufacturing and engineering teams. OEM, ODM, and private labeling requirements can be discussed for industrial equipment projects, subject to technical feasibility and order specifications.

3. Working Principle

An oil-injected screw vacuum pump uses rotating screw elements to draw gas into the pumping chamber and transport it toward the exhaust. During operation, injected oil assists with sealing internal clearances, lubricating relevant components, and removing compression heat. The discharged gas and oil pass through a separation process, allowing recovered oil to circulate within the system. The pump generates vacuum by continuously removing gas from the connected process, while the oil circuit requires appropriate maintenance and operating controls.

4. Technical Specifications

Technical Notes:

• The ultimate pressure for OSV1100–OSV5400 is shown as 60–80 Pa in the supplied specification sheet and should be confirmed before final publication.

• Dimensions and weights are based on the supplied series data.

• Electrical supply requirements, flange standards, oil specifications, performance curves, and installation conditions should be confirmed with AIRIPA before ordering.

• Nominal pumping speed does not represent constant pumping speed across all operating pressures.

5. Industrial Applications

The OSV series can be evaluated for a range of industrial vacuum processes, subject to operating pressure, gas composition, and equipment compatibility.

• Industrial Vacuum Packaging: Vacuum generation for compatible packaging machinery and production systems.

• Vacuum Drying and Processing: Gas removal from suitably designed industrial drying and processing equipment.

• Centralized Vacuum Supply: Vacuum generation for industrial systems with defined operating pressure and gas-load requirements.

• OEM Vacuum Equipment Integration: Integration into industrial machinery and custom vacuum systems requiring model-specific pumping capacities.

Applications involving significant condensable vapors, particulates, corrosive gases, flammable substances, or other hazardous process media require additional engineering review and suitable protective equipment.

OSV590–OSV880: 588–876 m³/h

These models provide the lower pumping capacity range within the OSV family, with motor ratings from 7.5 to 15 kW and a specified ultimate pressure of 30 Pa. They can be evaluated where the required gas load falls within their operating capabilities.

OSV1100–OSV1800: 1,062–1,812 m³/h

These four models provide intermediate nominal pumping capacities with motor ratings from 18.5 to 37 kW. They offer different capacity choices for industrial equipment and vacuum system integration.

OSV2600–OSV5400: 2,640–5,400 m³/h

7. Frequently Asked Questions

Q1. What is the pumping speed range of the AIRIPA OSV series?

The OSV series includes 11 models with nominal pumping speeds from 588 to 5,400 m³/h. The required model depends on the operating pressure, gas load, and other process conditions.

Q2. What is the difference between an oil-injected screw vacuum pump and an oil-free screw vacuum pump?

An oil-injected screw vacuum pump uses oil within its pumping mechanism to support sealing, lubrication, and heat removal. An oil-free dry screw vacuum pump operates without oil injection into the pumping chamber. Each design has different process compatibility and maintenance considerations.

Q3. How do I select the correct OSV vacuum pump model?

Start with the required operating pressure, process gas characteristics, gas flow, and evacuation time. Compare these requirements with the relevant model's pumping speed curve, ultimate pressure, and connection specifications rather than selecting by nominal pumping speed alone.

Q4. Does the OSV series require lubricating oil maintenance?

Yes. Oil-injected screw vacuum pumps require oil management and maintenance. The correct oil specification, service interval, and maintenance procedures should follow the manufacturer's operating documentation.

Q5. Can an OSV oil-injected screw vacuum pump handle water vapor or process gases?

Suitability depends on the gas composition, vapor concentration, temperature, operating pressure, and pump configuration. AIRIPA should review the process requirements before confirming compatibility or recommending protective accessories.

Q6. Does AIRIPA provide OEM and ODM services for the OSV series?

Yes. AIRIPA supports OEM, ODM, and private labeling discussions for industrial equipment manufacturers, distributors, and vacuum system integrators. Specific customization options are subject to technical evaluation and commercial agreement.
