CIP pump under-performing?
Dairy and pharma CIP systems need the right flow, temperature and pump. We supply and repair hygienic CIP circulation pumps.
CIP flow and heat explained
Flow: velocity is the rule
CIP works by velocity and chemistry: the wash must move at 1.5–2 m/s in lines to scour soil, and sprayballs need 10–20 m³/h each to cover tank surfaces. Line flow = velocity × pipe cross-section — a 2-inch line at 1.8 m/s moves about 13 m³/h. The calculator converts your velocity and pipe size to the flow the CIP supply pump must deliver.
Every branch in the circuit needs that minimum velocity, so the pump is sized for the worst branch, and circuits are usually cleaned one line at a time.
Heat: the wash budget
Heating the wash is the biggest CIP energy cost. Energy = volume × 4.18 kJ/kgK × temperature rise: 2000 L heated 55 °C needs about 460,000 kJ, or 128 kWh — roughly ₹830 at ₹6.5/kWh before recovery. Recovering heat from the rinse and using insulated tanks cut this by half on many plants.
The calculator returns kJ, kWh and the rupee cost for your volume, ΔT and tariff.
Pumps for CIP
CIP circulation pumps are hygienic centrifugal pumps in SS316 with food-grade seals, sized for the circuit flow at 1.5–2 m/s. The return pump handles the soiled wash back to the tank.

Technical & Operational FAQs
Q1.What flow rate does CIP need?
Enough to hold 1.5–2 m/s in the largest line being cleaned — a 2-inch line needs about 13 m³/h. Tanks cleaned by sprayballs need 10–20 m³/h per ball. Size the CIP pump for the worst branch in the circuit.
Q2.How do I calculate CIP heating energy?
Energy (kJ) = wash volume (L) × 4.18 × temperature rise (°C). For 2000 L heated 55 °C: 2000 × 4.18 × 55 = 459,800 kJ = 127.7 kWh. Multiply by the tariff for the cost — about ₹830 at ₹6.5/kWh.
Q3.What velocity should CIP lines run at?
1.5–2 m/s in lines — below 1.5 m/s soil is not scoured; above 2 m/s you waste pump energy and risk water hammer. Sprayball circuits follow tank-coverage flow, not line velocity.
Q4.How do I size the CIP supply pump?
Flow = the highest branch requirement (line velocity or sprayball demand). Head = pressure drop through the worst circuit plus sprayball pressure (typically 1–3 bar). Use the chemical pump sizing calculator with SS316 hygienic materials.
Q5.Why is my CIP failing inspection?
Check flow and temperature at the farthest point: below 1.5 m/s or below the target temperature means poor cleaning. Also check sprayball holes for blockage and the return line for air locks. A simple flow check with this calculator isolates the cause.
