Hot Oil Circulation Pumps with Magnetic Coupling
Hot Oil Sealless Pumps
Hot oil pumps play a crucial role in various industries, offering reliable solutions for the circulation and transfer of heated fluids. Selecting the right hot oil pump manufacturer and hot oil circulation pump supplier is essential to ensure efficiency and safety in your operations. At Dickow Pump Company, Inc., we specialize in hot oil sealless pumps designed to meet the demands of diverse applications.

What Are Hot Oil Sealless Pumps?
Hot oil sealless pumps are specifically engineered to handle high-temperature fluids without the risk of leakage. Unlike traditional pumps, these units operate without mechanical seals, which minimizes maintenance and enhances operational reliability.

Their innovative design allows for continuous flow while reducing the risk of contaminants entering the system. This feature is particularly advantageous in industries where cleanliness and efficiency are important. Magnetic coupled DICKOW-pumps of the series NMX/PRMW are of sealless design. The containment shell forms a closed system with a hermetically sealed liquid end.

Applications of Hot Oil Sealless Pumps
The magnetic driven NMX/PRMW-pumps are designed for hot oil applications, to improve plant and personnel safety in industrial heating plants. Mechanical seals are eliminated. No utility cooling needed. In these cases, double mechanical seals are required in conventional pumps.

These hot oil pumps are widely used in various sectors, including chemical processing, food production, building materials, and petrochemical industries. They are essential for heating processes, maintaining optimal temperatures in reactors, and facilitating heat transfer in production lines. In environments where safety is a priority, explosion-proof oil pumps are often required to prevent hazardous incidents. Our hot oil pumps are designed to meet these strict safety standards, ensuring peace of mind for operators.

Advantages of Hot Oil Sealless Pumps
Hot oil sealless pumps offer numerous advantages that set them apart from traditional pumps. One significant benefit is the reduction in maintenance requirements. The absence of seals means less wear and tear, leading to extended service life and lower operational costs. Dickow has had hot oil pumps in service for over twenty years, without having to be pulled for maintenance.

These hot oil pumps also provide enhanced safety by minimizing the risk of leaks, which can lead to costly downtime and potential hazards. The efficient design also promotes energy savings, making them an eco-friendly option for businesses looking to reduce their environmental impact.

Safety Features of Our Explosion-Proof Oil Pumps
We know that safety is a top priority. Our pumps are designed with multiple safety features that comply with industry regulations. These pumps undergo rigorous testing to ensure they can withstand extreme conditions while preventing leaks and other safety hazards. Investing in our pumps means investing in the safety and efficiency of your operations.

Why Sealless?
Why Use Dickow Magnet Drive Pumps?
Since the 1970s concern for the environment has become increasingly important in the design of industrial plants. Today this issue is a vital concern in any discussion involving new plants and updating of facilities. Equipment designers, engineers, and suppliers must offer solutions which will eliminate any adverse environmental impact, or at a minimum reduce it to sustainable or regulated levels.

The weakest link with respect to centrifugal pumps is the shaft seal, when considering release of fluids to the environment. This is because there is always some inherent emissions from mechanical seals. The average emission rate of a mechanical seal is 0.13 GPM to 0.35 GPM, and although this appears to be quite small, the actual atmospheric penetration is quite large when one considers that large chemical plants have thousands of pumps in operation. In 1989 the Environmental Protection Agency (EPA) published its first report on environmental pollution. The report documents that American chemical and petrochemical industries, in 1987, emitted 390 tons of toxic materials into the atmosphere, in part attributable to pump leakage.

Potential problems occur by the formation of dangerous explosive mixtures, which become worse when toxic or malodorous gasses and vapors endanger plant personnel. In order to prevent the vaporization of liquids between seal faces additional cooling is required when the media has vapor pressure greater than atmospheric pressure at operating temperatures. Additionally, when handling fluids that crystallize in the atmosphere, an appropriate quench connection or barrier fluid must be provided.

Various attempts have been made to improve the performance of mechanical seals in order to meet regulations pertaining to emissions. Examples include double acting mechanical seals of "tandem design", "back-to-back design", and various gas seal types. All of these require auxiliary equipment, systems, and controls. For many applications the costs of this equipment is not justifiable in light of the gains attained.

It would appear that the outer limits have been reached for improvements in mechanical seals with regard to reliability and emissions control. The only realistic solution is a sealless pump with zero leakage, i.e. without the connection of the media to the environment due to the absence of a seal. Many of our earliest customers installed Dickow sealless magnet drive pumps for their zero leakage feature, but quickly realized that their mean times between failures was greatly improved as down time due to seal replacement was eliminated completely.
