BPH/DPH e BMH/DMH by DAB are wet rotor circulators. They are designed for the circulation of water in civil and commercial conditioning and heating systems. The BPH/DPH (two pole motor) e BMH/DMH (four pole motor) circulator motor shaft can be manually deblock. BPH and BMH are the version with the single motor while BMH e DMH corresponds to the circulators in the twin configuration. Flanged suction and delivery ports. All the models have an air vent plug. The twin version is supplied as standard with an automatic suction type valve incorporated in the delivery port to avoid water recirculating through the unit when it is not running; and a blank flange for servicing either of the two motors. 

Only for Extra EU markets.

NKV 1, 2, 3, 4 are AISI 304 stainless steel multi-impeller vertical centrifugal pumps with coupling; designed for pressurization and heating circulation in civil and commercial environments, they can also be used in agriculture and in watering systems. All models with NKV 10, 15, 20 S have the parts in contact with the liquid in AISI 304 stainless steel. The models with NKVE 32, 45 have the pump body and upper flange in cataphorized cast iron. The impellers, diffusers and pump casing are in AISI 304 stainless steel. One protection group per units. Delivery check valve, pressure transmitter and expansion vessel for each pump. On request, X  version with materials in contact with water in stainless steel AISI 316. The groups are supplied assembled, set and tested directly at the factory. IE3 electric motors.
