DELEEMA INDUSTRIAL SOLUTION HOLDING COMPANY LIMITED

Transmitting · Filtering · Firing - Integrated Industrial Solutions from China

DELEEMA Industrial Solution Holding Company Limited is a China-based industrial supplier specializing in three core product lines: Air-operated diaphragm (AODD) pumps, activated carbon, and refractory kiln furniture. Headquartered in HENAN with production and sourcing roots dating back to the late 1990s and 2015 for our refractory lines, we combine lean manufacturing, in-house R&D, and rigorous quality control to deliver reliable, cost-effective equipment to customers across more than a dozen global regions, including North America, South America, Europe, Southeast Asia, the Middle East, and Africa.

Why Choose Us:

-- Full-Chain Manufacturing Capability - Our facilities include an R&D laboratory, testing equipment, a quality control department, a CAD design team, and an injection molding center, allowing us to develop, test, and refine products in-house rather than relying on third parties.

-- Certified Quality - Our products carry ISO9001 and CE certifications, and every finished unit undergoes 100% inspection (visual and functional) before shipment.

-- OEM/ODM & Full Customization - From sample-based replication to full custom design, we tailor pumps, carbon products, and refractory shapes to each customer's exact specifications.

-- Global Trade Ready - We support all major Incoterms (FOB, EXW, CIF, DDP, DAP, and more), flexible payment terms (T/T, L/C, Western Union, PayPal), and typical lead times of 15 working days.

-- Experienced Across Industries - Our equipment is deployed in automotive, aerospace, chemical processing, food & beverage, pharmaceuticals, electroplating, papermaking, mining, wastewater treatment, power generation, and more.

Our Product Strengths

1. Air-Operated Double Diaphragm (AODD) Pumps

Our diaphragm pumps use compressed air rather than a mechanical shaft to drive the diaphragm, which reduces mechanical stress, extends diaphragm life, and allows the pump to run dry without damage.

Key advantages:

--- Handles clean fluids through to high-viscosity slurries and large solid particles without damage.

--- Available in Bolted Metal, Bolted Plastic, and Clamped Metal configurations --- Metal and plastic wetted-part options (aluminum, ductile iron, stainless steel, polypropylene, PVDF) for corrosive and abrasive media.

--- Sizes from 1/4" to 3", supporting flow rates from a few liters to over 900 LPM.

--- Specialized variants for semiconductor-grade high-purity chemicals, food-grade sanitary applications, and filter-press/sludge dewatering.

--- ATEX-suitable options for flammable fluid handling.

2. Activated Carbon

Produced from wood, coal, and coconut shell, our activated carbon products meet national standards and serve a wide range of purification needs:

--- High adsorption capacity for water treatment, air purification, and gas desulfurization

--- Available in granular, powdered, and pellet forms, plus activated alumina and composite desulfurizers

--- Applications spanning industrial wastewater treatment, flue gas desulfurization, and pharmaceutical decolorization

3. Refractory Kiln Furniture

Built on Silicon Carbide (since 1999) and Mullite Cordierite (since 2015) production lines, developed in cooperation with a national Refractory Material Institute:

--- High thermal shock resistance and structural stability at temperatures up to 1400° C

--- Sic plate products offering up to 20% energy savings and a service life of 200+ firing cycles

--- Wide product range: Sic plates, beams, rollers, Mullite Cordierite batts, saggars, crucibles, fire bricks, and fully customized shapes

--- Proven track record supplying ceramic and sanitaryware kilns across South America, Southeast Asia, and South Asia/Middle East markets

Our Philosophy:

Service as the foundation, quality as the lifeline, innovation as the driving force.
