4 Unique Features of Rola Chem Dosing Pumps

	Chemical is never in contact with the mechanics of the pump. No contamination of the chemical or the pump.
	The pump has no moving parts like valves, seals, glands, etc. Minimal service and low maintenance.
	Self-priming. Does not loose prime. Reliable and consistent operation.
	Dry running causes no problem. Should pump run dry, no damage is caused to the pump.

All Rola Chem Systems

Inject chemicals in the "return" line, after the filter, to avoid any possible damage to the
     heater or other pool equipment
Are available in a wide range of flow outputs from 0.02L to 30L per hour, to suit all sizes of
     pools and spas
Can be used in salt or fresh water
Are adaptable for use with other sanitisation equipment like salt chlorinators, ozonators,
     ionizers, etc.

Rola Chem pumps work on the principle of positive displacement of chemicals and do not rely on "suction". They are self-priming, do not loose prime, and cause no damage to the pump should the pump run dry.

Due to a policy of continuous product improvement and development, specifications may be subject to change without notice.
