The often overlooked "maintenance timing" in the daily use of pumps. Regular inspections are essential to avoid reducing production efficiency. We are offering a flyer summarizing situations where "maintenance is necessary when these symptoms appear." Please check it out from the catalog download. Additionally, we offer a range of "pump units" for high-pressure plunger pumps, which are actively used in a wide variety of applications such as "reverse osmosis membranes (RO)," "high-pressure mist systems," "tank cleaning," "plant cleaning," "food processing plants," and "machining factories." *For more details, please refer to the catalog. Feel free to contact us as well.

The "high-pressure plunger pump" features valves, valve seats, and valve springs made of corrosion-resistant stainless steel. To enhance durability, the high-pressure seal is designed to be lubricated and cooled by the fluid being used. The valve mechanism has a cassette structure that allows for easy replacement. It can be used in various industries, including food processing plants, machine shops, plant cleaning, reverse osmosis membranes, and tank cleaning, making it versatile for a wide range of applications. 【Features】 ○ Durable high-pressure and low-pressure seals that require no adjustment ○ Ceramic plunger offers excellent corrosion and wear resistance, enduring long hours of use ○ Plunger rod is made of stainless steel ○ Crankcase is made of lightweight and durable aluminum die-cast ○ Crankshaft is made of chrome-molybdenum steel, providing excellent durability ○ Generous bearing sizes are selected to extend the pump's lifespan For more details, please contact us or download the catalog.

A plunger pump is a pump that has suction and discharge strokes. The amount of water suctioned is proportional to the pump's input rotation speed. The pump itself cannot control the flow rate. Pressure control is performed by a pressure regulating valve or an unloader valve. 【Features】 ○ Use flexible piping for the piping immediately adjacent to the pump ○ Keep excess water, supply water, and cleaning chambers as far away as possible from the pump's suction inlet For more details, please contact us or download the catalog.

The "pressure regulating valve" can set a stable pressure that is unmatched. It can be used with multiple pumps and multiple gun nozzles. Pressure adjustment is easy by simply turning the adjustment screw. The pressure regulating spring is built into the spring cylinder, resulting in a simple exterior structure. 【Features】 ○ Dedicated pressure regulating valve for plunger pumps ○ Can set a stable pressure that is unmatched For more details, please contact us or download the catalog.

Maruyama is a manufacturer whose core competence is technology related to pumps. Founded in the 28th year of the Meiji era, we started as a pioneer in fire extinguisher manufacturing and have developed our business based on the technology cultivated through fire extinguishers. Over our long history of more than a century, our technology has culminated in "pumps." [Featured Products] - High-pressure plunger pumps - Pump accessories - Fully automatic parts washers - Pressure testing equipment For more details, please contact us or download the catalog.

This is a dedicated pressure regulating valve for plunger pumps. It is primarily a pressure regulating valve for equipment.

Are you fully prepared for heatstroke prevention? The peak of summer is still ahead! Let's start taking measures against heatstroke. We utilize the heat of vaporization of water sprayed at high pressure to lower the perceived temperature in the spray area. 【Features】 - The main unit can be anchored for stability. - Water supply to the pump is directly connected to the water supply, eliminating the need for a tank. - Equipped with an industrial pump for continuous operation. - High-pressure line filter protects the nozzles. - Standard equipped with an electromagnetic valve to prevent dripping from the nozzles and allows for easy activation. - Compact and easy to handle standard model operating on 100V. 【Applications】 - Heat island countermeasures at work sites. - Dust prevention and static electricity prevention in various factories and warehouses. - Fine mist cooling in barns, pigsties, chicken coops, and vegetable houses. - Humidification in printing factories, textile factories, and various storage facilities. - Landscape engineering for mist parks and event venues.

The "Ultra Fine Bubble Pump Unit" is a device that can efficiently generate a high concentration of a large number of ultra fine bubbles using only water and water pressure. The generation amount of ultra fine bubbles per 1mL is approximately 300 million with a single pass, and by increasing it through circulation operation, it is possible to generate around 5 billion bubbles. *Conditions such as pressure (measured value at 3MPa pressure and 20L/min discharge rate) 【Features】 ■Maximum discharge water volume is 20L/min ■Two types available: engine type for easy outdoor use and motor type compatible with saltwater ■Can be used even with fine foreign substances (less than 0.2mm) present ■The number of ultra fine bubbles remains almost unchanged even when using a 150m hose ■Compatible with various gas supply *For more details, please refer to the materials. Feel free to contact us with any inquiries.
