Screw pumps PSRP - general industry

PSRP screw pumps, also known as counter-rotating screw pumps, are a special screw pump design that allows for pumping liquids at low flow rates and high pressures. They are frequently used in the chemical, petrochemical, refining, and pharmaceutical industries.

Unlike standard screw pumps, PSRP pumps They have specially designed screws that work in opposite directions, which allows the pressure to be kept constant even with changing fluid flow.

Moreover, these types of pumps are more resistant to contamination and viscosity than standard screw pumps, making them ideal for working with difficult liquids such as thick glues, pastes, masses, etc.

PSRP pumps They are also more flexible than other types of pumps because they can be adjusted to different pressure and flow levels, allowing them to be tailored to different applications.

Like other types of pumps, PSRP pumps They have different types of drives, such as electric, combustion and float, which are tailored to the needs of a specific application.

It's important to remember that to ensure reliability and safety, it's important to properly match the PSRP pump to the application and to perform regular maintenance and servicing. Therefore, it's crucial to purchase pumps from reputable manufacturers and use qualified professionals for pump installation, maintenance, and service.

Another important aspect to consider when choosing a PSRP pump is its efficiency. PSRP pumps can be more or less efficient depending on their design and operation. To increase efficiency, some PSRP pumps utilize variable geometry flow systems, which allow the screw shape to be changed to increase efficiency.

AnalogyUnlike other pump types, PSRP pumps are important for safety and environmental protection. PSRP pumps, especially those used in the chemical and petrochemical industries, can move fluids that are potentially harmful to humans and the environment. It is therefore important to use appropriate safety measures, such as leak protection and pressure monitoring systems, and to adapt pumps to environmental requirements.

Operating costs are also an important consideration when choosing a PSRP pump. While the initial investment in such a pump can be expensive, long-term operation can be worthwhile thanks to its high efficiency and reliability.

Technical description

The single-screw pump belongs to the group of rotary displacement pumps with the ability to self-prime the pumped fluid. Its main operating elements are:

• steel rotor /A/ made in the shape of a single-start screw with a circular cross-section and a large pitch,
• stator /B/ made of elastomer /rubber/ with a two-start thread with an elongated hole cross-section and a double rotor pitch.

During pump operation, the rotor rotates and circulates within the stator, pumping the fluid. This is possible because, in each phase of the rotation, the suction area is separated from the discharge area by a seal line. The pump can reliably pump highly viscous fluids, including those containing rounded solids (with a maximum size dependent on the pump size), without any auxiliary equipment.
The pumps transport liquids continuously. The pumped liquids are not subjected to pulsating or centrifugal forces. Even the most sensitive products are pumped gently.
