[Development Case] Stainless Steel Spiral Pump

Durability that withstands high-temperature and sulfate springs for geothermal power generation construction in hot spring areas! Development of pumps that also feature high quietness.

This is an introduction to a case study on the development of a stainless steel spiral pump. In a hot spring area in Kyushu, the construction of a geothermal power plant (binary power generation) was underway. The pumps used here needed to be durable enough to withstand high temperatures and sulfate springs. Additionally, there were many accommodations and residences in the vicinity, so high quietness was also required for the equipment used. Therefore, the pump was manufactured using SUS316, which is resistant to corrosion and durable. Furthermore, at the time of delivery, noise tests (dB) and octave band analysis were conducted, and only those that met the noise standards were used. [Case Study] ■ Client's Requests and Challenges - Due to the construction of a geothermal power plant (binary power generation) in a hot spring area, durability to withstand high temperatures and sulfate springs was necessary. - Since there were many accommodations and residences nearby, high quietness was desired. ■ Proposal - Use of SUS316 material, which is resistant to corrosion and durable. - Conduct noise tests (dB) and octave band analysis at the time of delivery to meet noise standards. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study of Pump Introduction for Watering Trucks] Special Vehicle Manufacturer

Responding to short delivery times! Introducing case studies of pumps for special water spraying vehicles.

We would like to introduce a case study of a special vehicle manufacturer that implemented the "Stainless Steel Self-Priming Centrifugal Pump MAPS Type" from Maruhachi Pump Manufacturing. Pumps for special watering vehicles require corrosion resistance to salt, vibration resistance during operation, space limitations for installation, and self-priming capabilities to reduce tank loading time. Additionally, with the snow season approaching, a short delivery time was necessary. In response, our company modified the stainless steel self-priming centrifugal pump MAPS Type, accommodating two drive methods: belt drive powered by an engine and hydraulic motor drive, tailored to the mounting vehicle. This significantly reduced the installation space compared to conventional direct motor connection systems. [Overview] ■ Background - Corrosion resistance, vibration resistance, space-saving, self-priming capability, short delivery time ■ Solution - Special modification of the stainless steel self-priming centrifugal pump MAPS Type *For more details, please refer to the PDF document or feel free to contact us.

Cast iron self-priming centrifugal pump

A spiral pump that is easy to maintain, has a short delivery time, and is inexpensive. It can always maintain a speedy and high suction capability.

It features an easy-to-handle, rational design with high-quality reliability and durability, and in the case of disassembly, the impeller, shaft, and bearings can be removed as a unit without disconnecting the piping, making maintenance easy. Since it is equipped with a self-priming structure developed by our company that includes a vortex air-water separation mechanism, once the pump is filled with water initially, it will begin self-priming simultaneously with operation thereafter, maintaining a fast and high suction capability at all times. Because it is mass-produced using a standardized method, the delivery time is short, and it can be purchased at a low cost. We have adopted a semi-open impeller design, but for the SP type, a closed impeller assembly is also possible (the model will be SG type). The shaft sealing part is standardly equipped with gland packing or mechanical seal. The materials for the packing, gland packing, and mechanical seal, including the self-priming valve, can be changed depending on the handled liquid, so please consult us. For more details, please contact us or download the catalog.

[Case Study of Spiral Pumps] Proposal for Pumps Suitable for Cavitation Prevention

Even with low water levels and high-temperature liquid, we want to suppress cavitation with a land-based horizontal pump!

Since aluminum electrolytic capacitors are directly related to the safety and quality of automobiles, there is a demand for further improvement in their performance and quality. In the manufacturing equipment for aluminum electrolytic capacitors, vertical axis pumps of the tank type are used for transferring electrolyte liquid close to its boiling point (95°C). However, in the new product manufacturing process, the electrolyte liquid becomes even hotter, and it was found in internal tests by users that the existing pumps could not meet the required suction performance of NPSH.Av1.3m or higher, leading to cavitation. We received a consultation from users who wanted to consider a maintenance-friendly horizontal land pump that would not cause cavitation, instead of a tank-type pump. [Case Study] ■ Site: Aluminum electrolytic capacitor manufacturing factory ■ Challenge - To suppress cavitation even with high-temperature liquid at low water levels using a horizontal land pump ■ Proposal - Introduction of a low NPSH stainless steel vortex pump, MAP type ■ Effect - Achieved stable transfer of high-temperature liquid and reduction of initial and running costs *For more details, please refer to the PDF document or feel free to contact us.
