a maximum flow setting. This will prevent over-pumping and 
save energy costs. Over-pumping is common in 

hvac

 systems 

as pumps are typically oversized for the application. Pump 
controls can only control the flow to a minimum speed; thus a 
dry-contact relay is supplies which will close when maximum 
flow is reached, which can be used for an alarm or other device.

Maximum Flow Setting

 

5.7  quadratic curve control with minimum 

& maximum flow protection

This control mode combines the control logic of 

5.5 & 5.6

 

which takes the values of the quadratic control curve and 
protection for both the maximum & minimum flow limits. Pump 
controls can only control the flow to the motor limit or maxi-
mum / minimum speed limits of the unit, thus a dry-contact 
relay is supplies which will close when either the minimum or 
maximum flow is reached, which can be used for an alarm or 
other device.

5.8  parallel sensorless pump control (pspc)

This configuration maps the system quadratic control curve 
into the 

pspc

 controller where the controller intelligence 

ensures the system flow requirements are met, while stag-
ing the pumps on and off to maintain optimum pump energy 
usage. This is accomplished by operating the pumping units 
at the best pumping efficiency level for the required flow. This 
controller is available for all Design Envelope equipment to a 
total quantity of 

6

 units.

5.9  2*100% capacity split units

When duty / standby is specified, enter the total system flow 
into ACE Online or ADEPT, then select

 2*100%

 unit split for 

a superior customer value. The 

100%

 flow redundancy is still 

in place 

plus

 the onboard

 pspc

 will engage the second unit in 

parallel operation should it predict lower operating costs.

If second side power is locked out, the operating pump will 
operate alone on the control curve to

 100%

 design flow.

6.0 maintenance

6.1  general care 

Vertical In-Line pumps are built to operate without periodic 
maintenance, other than motor lubrication on larger units. A 
systematic inspection made at regular intervals, will ensure 
years of trouble-free operation, giving special attention to the 
following: 

• 

Keep unit clean 

• 

Provide the motor with correctly sized overload protection. 
Keep moisture, refuse, dust or other loose particles away 
from the pump and ventilating openings of the motor. 

• 

Avoid operating the unit in overheated surroundings (Above 

100°f/40°c)

warning

 

Whenever any service work is to be performed on  
a pumping unit, disconnect the power source to 

 

the driver, lock it off and tag with the reason. Any 

possibility of the unit starting while being serviced must be 
eliminated. If mechanical seal environmental accessories are 
installed, ensure water is flowing through the sight flow 
indicator and that filter cartridges are replaced as recommend-
ed. (See Armstrong files 

43.85

 and 

43.86

 for seal environ-

mental instructions).
