TECHNICAL INFORMATION

Pump performance curves - Savino Barbera mag-drive chemical metallic pumps

Standard curves: 50 Hz (60 Hz curves available on request). Maximum rated pressure: PN6 @ 20°C. The curves refer to tests with cold, clean water and a density of 1000 kg/m3 (ISO9906). Hydraulic performance may change in relation to changes in the characteristics of the liquid to be pumped.

	Q max m³/h	H max m w.c.	kW	Poles	Ø max impeller	ATEX rated
BM06	6	8	0.25	2	78 mm	Zone 1 e 2
BM10	12	11	1.1	2	96 mm	Zone 1 e 2
BM15	23	19	1.5	2	120 mm	Zone 1 e 2
BM31	32	24	2.2	2	133 mm	Zone 1 e 2

Special non-standard motors can also be mounted: in this case, we recommend that you contact our technical department.

MAGNETIC DRIVE COUPLING

SEALLESS PUMPS

The absence of dynamic seals and magnetic coupling between pump and motor, at least virtually, prevent external leakage. Their maintenance, however, is usually more expensive than with pumps with mechanical seals.

CONTACT-FREE

The external magnet, coupled to the motor shaft, conveys movement to the internal magnet which is attached to the impeller. As the motor shaft does not extend inside the pump body, the contact-free magnetic pump is incapsulated and protected from corrosion.

Metallic sealless mag drive pumps with ermetic design

CLEAN LIQUIDS ALWAYS

The thin plastic coating of the magnets and the closed channels of the impellers do not withstand liquids with abrasive solids and suspended particles, especially when metallic. Over-saturated liquids could also pose a problem for magnetic pumps.

METAL MAG-DRIVE PUMPS

In metal magnetic pumps, the body and impeller are made of AISI 316 (standard version). Bushings: Charged PTFE or graphite. O-ring: EPDM or FPM. Shaft: Hastelloy C-276. Construction materials by request: Hastelloy and Titanium.

SEALED PUMPS VS MAGNETIC PUMPS

Magnetic pumps are considered to be hermetically sealed pumps. Their presumed tightness must be scrupulously evaluated in relation to the characteristics of the liquid being pumped. The choice of mag-drive pumps can be influenced by incorrect installation habits rather than by real technical needs. Magnetically coupled pumps are often preferred to mechanically sealed pumps in the belief that the former are safer, but their use requires particular attention to specific working conditions.

ATEX CERTIFICATION

AND OTHER OPTIONS

BM magnetic drive chemical pumps are also available in versions for ATEX Zone 1 and ATEX Zone 2, for use in potentially explosive environments. Magnetic drive seal-less pumps with these characteristics can be used in areas classified as being at risk of explosion. In addition to ATEX certification, BM magnetic drive pumps (both plastic and metal) can also be equipped with other optional features such as: explosion-proof motors (Ex-d), 60 Hz motors, flanges, PP baseplates.
