Lotion Pump

WH-P0001 — the precision specialist. This pump is specified where dispensing accuracy is a functional requirement rather than a nicety: serums sold by concentration, actives dosed per application, and treatment products where too much is waste and too little is an unhappy customer.

Its metering chamber holds output tightly consistent across strokes and across the product's life, and the mechanism is built for long-term reliability so the last dose from the bottle dispenses as cleanly as the first. The design also primes quickly, reducing the frustrating dry pumps that plague cheaper closures.

Manufacturer-direct from Kam Ling with per-batch QC. For dosage-critical products we recommend a bench validation: send us your formula, we return WH-P0001 samples configured for it, and your lab confirms delivered volume before production begins.
