Why choose SPLANEY diaphragm pump
Jun 26,2025
SPLANEY series diaphragm pump, efficient and durable, leading the industry in innovation

Choosing an efficient and durable pump is crucial in the washing ingredients and fluid conveying industry. The SPLANEY MWH-18 series high flow maintenance free mechanical diaphragm pump is the industry's first solution specifically developed for high pH and high viscosity chemical batching needs. With excellent sealing, corrosion resistance, and stability, it helps enterprises achieve efficient operation.
Diaphragm pump vs. other types of pumps: more stable and efficient
Compared to peristaltic pumps and Venturi pumps, diaphragm pumps perform better in terms of durability, precise control, and maintenance costs.
-- Peristaltic pumps require frequent replacement of hoses due to direct fluid contact, which increases maintenance costs and poses a risk of contamination.
-- The Venturi pump relies on pressure difference for operation, which can easily affect delivery efficiency due to blockage or pressure changes, leading to unstable production.
-- The diaphragm pump adopts mechanical drive to ensure the stability of fluid transportation and can maintain efficient operation in high-pressure and high viscosity environments without frequent maintenance, greatly reducing operating costs.
