MHBN/MHCN Pumps
- Filter aid (kieselgur) dosing
OBL is a world leader in the manufactu-
re of metering pumps for FILTER AIDS,
used for wine, beer and fruit juice filtra-
tion. These are diatomaceous earths
known as Kieselgur. A range of pumps
is available including lip seal plunger
pump, mechanical diaphragm and
hydraulically actuated diaphragm. These
meet the general requirements for flow
rates and pressure (100 litres per hour,
26,5 GPH at 10 bar g, 145 PSI g).
HV Pumps
- High viscosity dosing
Specifically designed to handle high
VISCOSITY PRODUCTS the HV
pumps are available in packed plunger
version only with either spring or posi-
tive return mechanisms. These pumps
are capable of handling products with
a viscosity up to 55,000 cP with each
head capable of achieving flow rates of
up to 150 l/h (40 GPH).
CN Pumps
- Microdosing
These pumps are designed to handle
EXTREMELY LOW FLOW RATES
where continuous dosing is required.
These packed plunger pumps are able
to control down to addition levels of
15 ml/h (0.04 GPH) at a maximum
pressure of 40 bar g (600 PSI g) due
to the unique OBL packed plunger
design and the use of exotic materials
for valves components.
Pump type RCC 16 HV 50 DV
6 l/h 10 bar g.
Spring return mechanism.
Pump type RB 16 MA 36 OM
5 l/h @ 40 bar g
spring return mechanism.
Pump type MHBN100 PP
The type of pump that best
meets both the technical and
economic requirements is the
MHBN/MHCN versions.
These are specially designed
with PP heads, FDA silicone
seals and an AISI 316L seats
and balls coupled with the
OBL unique PTFE mechanical
diaphragm.
Pump type RCN 6A 70 TL
500 ml/h max capacity
40 bar g max pressure
1% step dial STD manual adjustment.
OM Pumps
- Magnesium oxide slurry dosing
These are designed for dosing diluted
MAGNESIUM OXIDE slurry into diesel.
Working with the manufacturers of the
magnesium oxide slurry, since 1980 the
OM pump has been specifically designed
with special wetted materials for this
application. It is available with both spring
and positive return mechanism (flow rates
up to 68 litres per hour, 18 GPH and
operating pressures up to 50 bar g, 725
PSI g).
Special Solutions
Z type actuator horizontally
fitted on XRN pump
(hydraulic diaphragm).
Detail of Analogical
reading (1% steps).
Z type actuator vertically
fitted on LX9 pump
(hydraulic diaphragm to
API 675 STD).
Z type actuator vertically
fitted on XL pump
((hydraulic diaphragm to
API 675 STD).
All OBL pumps, can be equipped with
Z type electrical actuator, with
following characteristics:
IP 66 STD (standard)
Manual emergency override
Anticondensation heather
(on demand)
Non standard voltages and
frequencies
External automatic/manual selector
Flow rate is adjusted according to
following input signals:
4-20 mA, 0-20 mA, 20-4 mA e 0-10 V
