Product Description

Product Description

(1)Features
Barrier pressure units of the SPA range 
perform all the functions of a barrier 
system essential for operating double 
seals (circulation and cooling of the barrier 
medium, pressurization of the barrier fluid 
and compensation of leakage). The SPA 
range is available in 3 basic versions:
SPA1000: tank capacity 40 l, flow rate 6 l/min.
SPA2000: tank capacity 100 l, flow rate 12 l/min.
SPA3000: tank capacity 100 l, flow rate 23 l/min.

The three SPA ranges are designed for 
hydraulic oil with viscosity values of 12 to 
90 mm2/s at operating temperature (tank 
temperature). The optimum viscosity of 
the class of the oil to be used has to be 
determined separately in accordance with 
the respective application.

(2)Advantages
• Max. operating temperature in the tank 80 °C (return line max. 90 °C)
• Temperature monitoring with a return line and tank thermometer
• Barrier fluid directed through oil cooler
• Reversible double filter (SPA1000: single filter)
• Manual control of barrier fluid pressure
• Relief valve for reducing barrier fluid pressure at standstill
• Level switch with contact for MIN level
• Measuring instrument connections suitable for fitting contact switching devices (NG160)
• Provision of an additional pressure connection for monitoring the pump discharge pressure (outside the circuit)

(3)Functional description
The barrier pressure for circulation is 
generated by a gear pump. The setpoint 
barrier pressure is set on an overflow 
valve in the mechanical seal return line. 
From this point on the barrier fluid flows 
back without pressure through a filter and 
a heat exchanger to the storage tank. To 
enable systems (pump, agitator) to be 
stopped without causing damage to the 
seal in the event of a malfunction (e.g. 
power failure, damaged motor, etc.), the 
barrier pressure unit can be fitted with a 
pressure accumulator unit. To prevent the 
pressure in the accumulator discharging to 
the pressureless storage tank, the return 
line has a pilot-operated check valve, and 
the supply line also has a simple check 
valve. The barrier pressure is retained for a 
limited time. However, no circulation takes 
place and no heat is dissipated from the 
mechanical seal. 

(4)Materials
• Storage tank, measuring instruments, cooler and piping are made of stainless steel
• Fittings, distributor units, shut-off valves and tank lid are made of galvanized steel

(5)Recommended applications
• Chemical industry
• Petrochemical industry
• Refining technology
• Oil and gas industr
