Lotion Pump

WH-215 B — the sealing-enhanced variant of the flagship. The B variant upgrades the WH-215 platform's gasket system and valve seating for tighter closure and even steadier dispensing volume, aimed at formulations and logistics chains that punish ordinary pumps.

Specify it for low-viscosity products prone to seepage, alcohol-based formulas, or shipments crossing large temperature gradients where expanding headspace air pushes liquid past lesser seals. E-commerce brands shipping without secondary sealing tape will notice the difference in their damage rates.

Because A and B variants share the WH-215 core, you can mix variants across SKUs while keeping one validated supplier and one spare-parts logic. Manufacturer-direct from Kam Ling — send us your formula's characteristics and shipping profile, and we will confirm whether B-level sealing is genuinely needed or the standard WH-215 already suffices.
