松田ポンプ製作所 List of Products and Services

Our company handles "corrosion-resistant slurry pumps" made of Pyromet and wear-resistant Pyron. To ensure corrosion and wear resistance, we differentiate between Pyron and Pyromet based on liquid composition, type and concentration of slurry, and temperature. The impeller is designed to move back and forth, allowing for sustained high performance, making it suitable for transporting high-concentration slurries. 【Features】 ■ Acid resistance and slurry wear resistance of SCS16 (SUS316L) or higher ■ Specially designed impeller ■ Suitable for transporting high-concentration slurries ■ No liquid leakage in the gland area ■ Structure allowing the impeller to move back and forth ■ Capable of equipping our designed mechanical seal for slurry (special specifications) *For more details, please refer to the PDF materials or feel free to contact us.

We handle rubber-lined "acid-resistant and abrasion-resistant vortex pumps." Through joint research with mechanical seal manufacturers, we have developed mechanical seals that can withstand various conditions, which are now standard specifications. For rubber materials, we apply hard rubber, soft rubber, and chloroprene, and for shaft sleeve materials, we use titanium and Hastelloy. For applications requiring corrosion and abrasion resistance, the use of Pyromet alloy as impeller material is also possible. 【Features】 ■ Excellent corrosion resistance, sealing function, and pump efficiency ■ Development of mechanical seals that can withstand various conditions ■ Application of hard rubber and soft rubber as rubber materials ■ Possible application of Pyromet alloy for corrosion and abrasion-resistant applications *For more details, please refer to the PDF document or feel free to contact us.

We handle acid-resistant valve-less pumps made of Swizen and stainless steel. Since it does not require priming water or a foot valve, you only need to inject liquid into the pump casing once at the beginning, and thereafter it can operate without priming water. Additionally, it can also be used as a vacuum pump, allowing for continuous supply of a small amount of liquid, thus functioning as an acid-resistant vacuum pump (maximum vacuum level 600mmHg). 【Features】 ■ No need for priming water or foot valve ■ Extremely strong self-priming capability ■ Can also be used as a vacuum pump ■ Capable of pumping fluids with a large amount of gas mixed in ■ Easy to prime large acid-resistant pumps *For more details, please refer to the PDF materials or feel free to contact us.

We handle the "Acid-Resistant Submersible Pump" with a rigid shaft and sinking type. In addition to being able to place the impeller in a safe position against cavitation, there are no issues with liquid leakage since there is no shaft sealing device. Moreover, it does not require priming, and the ON/OFF control of the liquid level is easy, making it suitable for automatic operation. We offer a variety of products, including the "Pylon Type A Submersible Pump for Concentrated Sulfuric Acid." 【Features】 ■ No issues with liquid leakage due to the absence of a shaft sealing device ■ Impeller can be placed in a safe position against cavitation ■ Special structure with forced lubrication type (Type A with liquid bearings) ■ Uses a thick shaft that has been thoroughly considered for dangerous shaft speeds (Type B without liquid bearings) ■ Capable of suctioning to the bottom in the state shown in fig-3 (Type BS) *For more details, please refer to the PDF document or feel free to contact us.

We handle "Molten Metal Pumps." Starting with molten lead, we have delivered a wide variety of pumps for various molten metals over many years. Through our extensive experience, we have achieved sufficient reliability for operation at high temperatures through well-improved structures and appropriate material selection. Additionally, the shaft, bearings, and especially the lower bearing section exposed to high temperatures are designed uniquely by our company, and we have a proven track record of trouble-free operation. 【Features】 ■ Well-improved structure and appropriate material selection ■ Sufficient reliability for operation at high temperatures ■ Unique design of the lower bearing section ■ Various models available for small to large flow rates *For more details, please refer to the PDF materials or feel free to contact us.

"Pyromet Alloy" is a special stainless steel developed and commercialized independently by our company for the purpose of corrosion and wear resistance. It features a ferrite + austenite dual-phase structure composed of 250r-5Ni-2Mo, including various grades such as the ferromagnetic "Pyromet 11." "Pyromet 11" is particularly suitable for sulfuric acid plants handling concentrated sulfuric acid and fuming sulfuric acid, as well as for seawater and copper electrolysis plants. 【Features】 ■ Corrosion and wear resistance ■ Our unique special stainless steel ■ A wide range of grades available *For more details, please refer to the PDF materials or feel free to contact us.

Our company handles the "Non-Leak Acid Slurry Pump." Through the integrated design of a mechanical seal for slurry and our patented vertical glandless pump, we have achieved a pump that has no leaks even with high-concentration slurries. The materials for the wetted parts can be freely combined from various options such as acid-resistant and abrasion-resistant Swyzen, Pyromet alloy, rubber lining, and some ceramics, depending on the type of liquid and usage conditions. Additionally, there is no need for maintenance for one year even with high-concentration slurries, and disassembly is straightforward, allowing for extremely quick assembly and disassembly without removing the piping. [Features] - A pump with absolutely no leaks even with high-concentration slurries - No maintenance required for one year - Extremely quick assembly and disassembly - Vertical V-belt type as the basic model - Performance can be freely changed by selecting the rotation speed *For more details, please refer to the PDF document or feel free to contact us.

Our company handles titanium "acid-resistant pumps." We use titanium, which has excellent corrosion resistance against localized corrosion (such as pitting and crevice corrosion), as the metal material. The main types of shaft sealing devices include "Teflon bellows mechanical seals" and "outside mechanical seals." 【Features】 ■ Titanium pumps ■ Uses titanium, which excels in localized corrosion resistance ■ Suitable for chemical, pharmaceutical, and food industries *For more details, please refer to the PDF document or feel free to contact us.

Our company handles "acid-resistant vortex pumps" in both gland type and mechanical seal type. All wetted parts are made by Swagelok, ensuring complete corrosion resistance. The cast iron frame flange and cover hold the Swagelok casing and cover securely from both sides, providing structural reliability. The impellers are all semi-open type, preventing slurry blockages, and due to the action of the back vanes, there are no fluctuations from the gland during operation. 【Features】 - All wetted parts are made by Swagelok - Structurally reliable - No fluctuations from the gland during operation - Gland holder has a two-part structure - Easy replacement of gland packing *For more details, please refer to the PDF document or feel free to contact us.

This catalog introduces the products handled by Matsuda Pump, a specialized manufacturer of chemical pumps. It includes information on the materials of "spiral pumps," as well as the features, applications, and examples of each pump. For corrosion-resistant and abrasion-resistant pumps, please feel free to consult us. [Contents] ■ Spiral Pumps ■ Self-Priming Spiral Pumps ■ Axial and Mixed Flow Pumps ■ Non-Leak Pumps ■ Valve-less Pumps *For more details, please refer to the PDF document or feel free to contact us.

• Other pumps

We offer a vertical self-priming pump that combines the advantages of vertical non-leak pumps and horizontal self-priming pumps. Like non-leak pumps, even with high-concentration slurry, the slurry does not adhere to the shaft sealing area during operation. With many technologies cultivated from horizontal self-priming pumps, we ensure stable self-priming performance. 【Features】 ■ Complete shaft sealing ■ Self-priming performance *For more details, please download the PDF or contact us.
