LOW-PRESSURE DIAPHRAGM PUMP — COMET PUMP

BP70

BP 75 is the Comet diaphragm pump for low pressure, specifically designed for herbicide treatments and liquid fertilizer application in solution, applications that require high flow rates but do not need the typical pressure of an atomizer. Dal Degan uses it in wheelbarrows, sprayer carts, and platform units for herbicide application and low-pressure spraying on medium-sized areas. The three NBR diaphragm configuration (Desmopan® and Viton available upon request) ensures smooth delivery and long-lasting durability. The distinctive feature of the BP series compared to the APS series is the construction of liquid-contact parts in chemical-resistant plastic material against the chemicals typical of herbicides, liquid fertilizers, and aqueous solutions used in agriculture. The heads and manifolds are made of polyamide (nylon), a material that resists herbicide chemicals much better than aluminum in prolonged cycles. The pump is available with safety valve and p.t.o. protection upon request.
