SS 316 Rotary Gear Pump – Stainless Steel Chemical & Food Grade Gear Pump

1. The Crucial Link Between Fluid Viscosity & Motor Speed

Unlike standard centrifugal pumps that run at a high 2900 RPM, rotary gear pumps require variable speed configurations depending on how thick your liquid is:

• Thin Liquids (Chemicals, Water): Can be run at a higher speed via a standard 4-Pole induction motor (~1440 RPM).

• Thick, Viscous Liquids (Syrups, Honey, Heavy Oils): Must be run at lower speeds (200 RPM to 400 RPM) by coupling the pump to an industrial reduction gearbox motor. Running thick liquids too fast will cause cavitation, excessive vibration, and motor burnout.

2. Built-In Pressure Relief Protection

Because a positive displacement gear pump will continue building pressure as long as the gears are spinning, closing a valve downstream can cause catastrophic line pressure. We highly recommend installing an external pressure relief valve (PRV) bypass line or using an integrated relief valve model. This safely reroutes the liquid back to the suction tank if a downstream pipeline block occurs.

3. Simple Maintenance & Self-Priming Action

Our SS 316 series features exceptional self-priming capabilities, drawing a strong vacuum to pull fluids cleanly from lower collection levels. Maintenance is remarkably straightforward because the entire pump can be serviced by simply removing the back cover plate—meaning you can inspect or clean the internal gears without completely disconnecting the main pipe flanges from your production line.

Shipping & Logistics Information

At Hitech Pumps and Motors, we specialize in heavy-duty industrial equipment. Because of the weight and technical nature of our products, we primarily ship through trusted regional and national transport agencies to ensure your order arrives safely and cost-effectively.

1. Shipping Method: Goods Transport

Most orders are dispatched via reputed transport services.

• Door Delivery vs. Godown Delivery: Depending on your location and the transport service available, shipments may be sent for "Door Delivery" or "Self-Collection" from the transporter’s local godown.

• Tracking: Once the goods are dispatched, we will provide you with the LR (Lorry Receipt) number and the transporter’s contact details via WhatsApp or email.

2. Request a Particular Transport

We understand that you may have established accounts or preferred transporters that you trust.

• Custom Requests: You can request a specific transport agency for your delivery.

• How to Specify: Please mention your preferred transporter name and their Ahmedabad booking office details in the "Order Notes" section during checkout, or contact us immediately after placing your order.

• Compatibility: We will do our best to accommodate your request, provided the transporter has a booking office nearby and accepts industrial machinery.

3. Dispatch Timeline

• In-Stock Items: Orders are typically dispatched within 24 to 48 hours of payment confirmation.

• Custom Orders: For products requiring specific modifications (like special seals or motor couplings), dispatch timelines will be communicated individually.

4. Shipping Charges

• To-Pay Basis: Most transport shipments are sent on a "To-Pay" basis, where you pay the freight charges directly to the transporter upon delivery.

• Pre-Paid Shipping: If you prefer to include shipping in your invoice, please contact our sales team for a freight quote before finalizing your payment.

5. Transit Insurance & Damage

• Safe Packaging: We use industry-standard wooden crates or heavy-duty corrugated packaging to prevent transit damage.

• Inspection: Please inspect the external packaging for any signs of damage before signing the LR. If you notice significant damage, mention it on the LR copy and contact us immediately.

What makes this pump suitable for food-grade products?

It features 100% high-purity Stainless Steel 316 casing, gears, and shafts. This prevents fluid contamination and easily stands up to aggressive alkalis, DM water, and hygienic food-grade requirements.  

Does the viscosity of the liquid affect the pump speed?

Yes. Thin liquids can safely run at higher speeds (around 1440 RPM), but highly viscous liquids like syrups and heavy oils must be run at slower speeds (200 RPM to 400 RPM) to prevent cavitation, excessive vibration, and motor burnout.  

Do I need a pressure relief valve?

Because it is a positive displacement pump, it will continually build pressure as long as the gears spin. It is highly recommended to use an external or integrated pressure relief valve (PRV) to safely bypass liquid back to the suction tank if a downstream blockage occurs.  

CI or SS316 which one for my fluid?

CI for oils/fuels; SS316 for anything corrosive, edible or hygiene-critical.

BLOG

Can it pump mustard/edible oil? Sugar syrup? Honey?"

Yes, 20–225 LPM depending on size; syrup/molasses models run at reduced RPM with VFD.

Is the price different from CI?

Yes, SS316 costs more due to material; from ₹9,000 for the smallest model.
