SOLUTION CASES

CASE 1

The pump malfunctioned due to torrential rain, making operation difficult.

Product Used

SUAD-1010ED

The pump malfunctioned due to torrential rain, making operation difficult.

Due to torrential rain, the customer’s surface pump was flooded and malfunctioned, disrupting equipment operation.

The risk of flooding was mitigated with the use of a dry pit submersible pump

“We proposed an amphibious, dry pit type submersible pump, effectively reducing the risk of operational disruptions during flooding.
Originally designed for underwater use, the pump’s design was also adapted for dry-pit applications, providing the following benefits:”

Specific Effects

Improved flood resistance
Even when submerged, the pump continues to operate without failure, ensuring stable performance.
Reduced risks
The risk of troubles during torrential rain events was significantly reduced.
Lower operating costs
Costs associated with flooding-related malfunctions and repairs were reduced.

As a result, we achieved safer, more stable equipment operation, capable of withstanding unforeseen weather conditions.

CASE 2

Proposal for a high-temperature submersible pump capable of withstanding liquid temperatures of 100°C

Product Used

CSU5-2030EVVQ

Challenges in the maintenance and management of pumps handling high-temperature liquids

Due to the need for a pump that could handle the transfer of high-temperature liquids exceeding 90°C, a vertical shaft pump was being used. However, aging had become a concern, resulting in increased costs and effort for maintenance and management.Therefore, there was a need for a pump that could not only handle liquid temperatures above 90°C but also support more efficient operation.

Cost reduction and shorter installation period through the introduction of submersible pumps

We proposed a stainless steel submersible pump designed for high-temperature liquids, capable of withstanding 100°C. This product is equipped with the following features:

Specific Effects

High-temperature liquid compatibility
A structure capable of withstanding liquid temperatures up to 100°C. Achieves stable operation under high-temperature conditions
Enhanced durability
Using stainless steel enhances corrosion resistance, enabling long-term use
Reduction in running costs
Fewer parts are required compared to vertical shaft pumps, achieving lower maintenance costs

Additionally, the adoption of a center flange design allows for suspended installation, enhancing installation convenience.
The stainless steel 100°C specification submersible pump has been introduced at multiple sites, all of which have received high praise.

CASE 3

Proposal for a submersible pump with modified key materials

Product Used

SE5-82LET

Corrosion protection was necessary, but an all-stainless steel solution exceeded the budget.

Given the liquid’s properties and the need for corrosion resistance, the customer sought to adopt an all-stainless steel submersible pump. However, the high cost exceeded their budget.

By partially incorporating stainless steel, we successfully reduced costs while effectively addressing the issue.

By replacing only the corrosion-prone pump components with stainless steel, we achieved both durability and cost reduction. As a result, the following benefits were achieved:

Specific Effects

Cost reduction
Compared to the all-stainless steel specification, using the stainless steel only where necessary allowed us to make proposals within budget.
Ensuring corrosion resistance
By making the pump components that were most prone to corrosion out of stainless steel, we were able to improve the pump’s adaptability to the liquid’s properties and extend its lifespan.

By leveraging EIM’s unique wide range of customization options, we tailored the specifications to meet the users’ specific requirements, achieving the optimal solution.

CASE 4

FM approved explosion-proof submersible motors (U.S. & Canada)

Product Used

EMQY-Series

A certified explosion-proof product is required.

Among North American pump manufacturers, there was a growing demand for Factory Mutual (FM) explosion-proof motors to be installed in their own submersible pumps.
The FM explosion-proof standard is the most widely used fire prevention certification in the U.S., and pump equipment that requires this standard must use compliant explosion-proof products.

Meeting customer needs with products certified for explosion-proof compliance

Leveraging the explosion-proof and submersible motor technologies developed over the years, EIM has obtained the FM explosion-proof approval to meet customer demands and has released the EMQY Series.

Specific Effects

The EMQY Series has the following features.

High performance and durability
Delivers stable performance even in harsh environments, ensuring long-term use.
Reliability
Meets FM explosion-proof standards while enhancing the safety of the integrated submersible pump.

This has consequently played a significant role in helping North American pump manufacturers expand and develop their markets.
EIM currently supplies the EMQY Series to more than 10 companies in the U.S., with an impressive annual sales record of over 400 units. Customers have expressed high satisfaction with its performance and durability.

CASE 5

Proposal of a large solids handling submersible pump

Product Used

SV-1035EQT

Necessity to reduce damage caused by jellyfish

The existing vertical shaft pump in the seawater intake system frequently clogged due to jellyfish, resulting in reduced operational efficiency and high maintenance costs. As a result, a pump capable of efficiently handling jellyfish while preventing clogging was needed.

Minimizing clogging from jellyfish and other debris by using a pump with a large solid passage

To address jellyfish clogging problems, we offer pumps with a large solid passage. Among these, we proposed the horizontal submersible sand pump.

Specific Effects

Improved solid handling capacity
The large foreign matter passage diameter allows for efficient transfer of floating objects such as jellyfish. This significantly reduced the frequency of blockages.
Suitability for collecting surface-floating debris
The suction inlet is designed horizontally, allowing for easy collection of surface-floating debris when the installation method is optimized. This design ensures excellent performance for jellyfish intake.
In addition, considering the possibility of corrosion from seawater, sacrificial anodes and anti-corrosion coatings were applied to enhance durability. The first proposed unit was highly praised, leading to a decision to upgrade all remaining equipment (over 10 units) to horizontal submersible sand pumps.

This upgrade has reduced maintenance frequency and costs while improving operational efficiency.
