In fluid transfer, it is important to consider three main aspects: the characteristics of the fluid to be transferred (fluid information), the selection of equipment that meets the desired conditions (equipment selection), and the compatibility with the site (external factors). Among these, "fluid information" requires careful consideration of various factors such as the fluid's special properties, viscosity, specific gravity, corrosiveness, and temperature when making selections. This document focuses on temperature and corrosion resistance, summarizing cases of fluid transfer at temperatures above 50°C, which are considered difficult with standard products. We invite you to read it. [Published Cases (Excerpt)] ■ Up to 80°C - Major steelworks in the Kanto region - Major food factories - Automotive parts factories - Recycling plants *For more details, please refer to the PDF document or feel free to contact us.

In the pump transfer operation, IN/OUT is essential. Broadly speaking, there are submersible pumps and surface pumps, but submersible pumps mainly operate while submerged in the fluid, so they generally do not have self-priming capabilities. On the other hand, self-priming pumps are mostly found in surface pumps, and they are equipped with check valves or mechanisms that serve that purpose near the pump's interior or suction inlet. Pumps that have the ability to draw in fluid are collectively referred to as self-priming pumps. This document summarizes fluids that were actually self-primed by H2's self-priming pumps, as well as fluids that can operate under conditions close to self-priming. Please take a moment to read it. [Contents (partial)] ■ Machine oil ■ Ceramic slurry ■ Polymer coagulants *For more details, please refer to the PDF document or feel free to contact us.

As the quality and variety of convenience store bread continue to increase year by year, production factories are required to ensure accurate and efficient operations while also considering the "ease of work" for their employees. Due to the challenges of efficient production and reducing work load, we received inquiries from major convenience store bread factories, and they adopted A2's pump for the process of transferring custard. Since custard cream is transferred at low temperatures and is almost solid, we selected the sanitary air diaphragm pump "SB series" as the transfer pump. Although the initial self-priming took a bit of time, it generally demonstrated satisfactory transfer capacity for the customer, and its lightweight and compact design were well received, with easy disassembly and cleaning being highly praised. In this document, we visited the factory where our pump was actually adopted and inquired about the challenges and background of the request. For more details, please download the document and check it. [Overview] ■ Delivery: Major convenience store bread manufacturing factory in Saitama Prefecture ■ Application: Transfer of custard cream (with control) ■ Model: Sanitary diaphragm pump SB type
