CAUTIONS & WARNINGSBASIC TROUBLESHOOTINGSUGGESTED INSTALLATION

PUMP TEMPERATURE LIMITS:

PVDF and Polypropylene 4°C – 79°C (40°F - 175°F)

CAUTION: Maximum temperature limits are based upon mechanical

stress only. Certain chemicals will signiﬁ cantly reduce maximum safe operating temperatures. Consult Chemical Resistance Guide for chemical compatibility and temperature limits.

CAUTION: Do not exceed 6.9 bar (100 psig) air supply pressure.

CAUTION: Verify the chemical compatibility of the process and cleaning

ﬂ uid to the pump’s component materials in the Wilden Chemical Resistance Guide.

CAUTION: Plastic series pumps are made from plastic that is not UV-

stabilized. Direct sunlight exposure for prolonged periods can cause deterioration of plastic.

CAUTION: V2550 pumps are not submersible.

CAUTION: Always wear safety glasses when operating pump. If

diaphragm rupture occurs, ﬂ uid being pumped may be forced out air exhaust.

WARNING: Before any maintenance or repair is attempted, the

compressed air line to the pump should be disconnected and all air pressure allowed to bleed from the pump.

WARNING: Ensure that the air supply line is clear of debris. Use of a 5µ

(micron) in-line air ﬁ lter is recommended.

Suction-lift curves are created using pumps operating at 305 m (1000’) above sea level. This chart is meant to be a guide only. There are many variables which can affect the pump’s operating characteristics.

Suction lift can be affected by the number of intake/discharge elbows, viscosity of pumping ﬂ uid, elevation (atmospheric pressure), pipe friction losses and other factors.

Caution: Do not exceed 6.9 bar (100 psig) air supply pressure.

SUGGESTED INSTALLATION

PUMP SELECTION: Ensure that the pump materials of construct ion are compa tible with the pumping media and the immediate surrou ndings the pump will be subject ed to. Refer to the Wilden Che mical Resis tance Guide . For optimum li fe and perf ormance, the pump s ize should be speci ﬁ e d so that dai ly operat ion param eters ar e not near th e pump’s max imum rat ed perfo rmance capabilities.

INSTALLATION: The Velocit y pump has two foot-mount conﬁ gurations and can be mounted in any or ientat ion. The pump can be mount ed in place or lef t free standing for use in multiple locat ions. If t he pump is to be mount ed in place, it is suggested to at tach the Base Assembly to the desired horizont al or vertical surface using four ( 4) screws (not supplied ) and then at tach the pump to the Base Assembly (See Assembly Ins tructions).

The Velocity pump has two inlet ﬂ uid connections and two discharge ﬂ uid connections. One inlet and discharge connec tion must b e plugged using the supplied NPT plugs.

PIPING: The suction and discharge piping diameter should be equivalent or larger t han the diame ter of pump connect ion, the length and complexit y of the suct ion and discharge piping shoul d be minimized, unnecessary elbow s, bends and ﬁ t tings should be avoided, all in an e ff ort to reduce friction los ses.

The suction hose must be non- collapsible. If rigid piping is used , it should be supported independen tly of the pump. I n addition, the piping should be aligned to avoid placing s tre ss on the pump ﬁ t tings.

Whe n used in self -primi ng applicat ions, it i s critic al that all ﬁ tting s and connec tions are ai rtigh t or a reduc tion or loss of pump suct ion capabili ty will r esult. E nsure that the suctio n lift requirement is within the pump model’s capabilit y.

AIR SUPPLY: Every pump should have an airline large enough to supply the volume of air necessary to achieve the desir ed pumping rate. Air pr essure to t he pump shoul d not exceed a maximum of 6.9 bar (10 0 psig ). For best results, t he pumps should use a 5µ (micron) air ﬁ lter to eliminate air-li ne contaminant s, a needle valve and p ressure regulator.

SOLENOID CONTROL: When s tar t-s top operation of a st andard air val ve equipped pump is cont rolled by a so lenoid valve in the air line, a thr ee-way ( 3/2 ) solenoid valve sh ould be used to vent pressurized air be tween the solenoid and pump w hen the pump is stopped.

PUMP OPERATION : Once ins tallation is complete, pump operation can be s tar ted by opening the ai r shut-o ff val ve (do no t exceed the p ump’s max imum ra ted pres sure) . The pr essure r egulato r and needle valve are used to adjust the speed of t he pump.

BASIC TROUBLESHOOTINGSUGGESTED INSTALLATION

Pump will not run or runs slowly:

1. Ensure the air inlet pressure is 0.3 bar (5 psig) above the start-up pressure of

the pump.

2. Ensure the differential pressure (dif ference b etween the air inle t pres sure and

ﬂ uid discharge pre ssure) is not less than 0.7 bar (10 psig) .

3. Check air line /ﬁ lter for blo ckage/ debris. Check for obstruc tion in the air

passageways of the p ump.

4. Check for objects in the pump that would obs truct the movement of internal parts.

5. Check for severe air leakage (blow -by) c oming f rom the air exhaust. This could

indicate a failed O-ring s eal or worn air valve assembly.

6. Inspe ct for check valve failure. A worn check ball can get stuck in the seat. A chec k

ball can swell and bec ome stuck if not compatible with ﬂ uid pumpe d. Replace if nece ss ar y.

Pump runs but little or no product ﬂ ows:

1. Check for cavitation. Conﬁ rm vac uum required to lif t the ﬂ uid is not greater than

the vapor pres sure of the ﬂ uid being pumped. Slow pump spe ed to allow viscous ﬂ uids to ﬂ ow into liquid chambers.

2. Ensure that the suction lift requirement is within the pump model’s capability.

3. Inspect for check valve f ailure. A worn check ball can get stuck in the seat . A check

ball can swell and bec ome stuck if not compatible with ﬂ uid pumpe d. Replace if nece ss ar y.

Air bubbles in pump discharge:

1. Check for ruptured diaphragm.

2. Check tightness of outer piston to shaft.

3. Check integrity of O -ring seals, especially intake side of manifold.

4. Ensure pipe connections are airtight.

Product comes out of air exhaust:

1. Check for ruptured diaphragm.

2. Check tightness of outer piston to shaft.
