Products Description
The chemical process pump is a horizontal, single-stage, single-suction centrifugal pump with a volute casing and cantilever design. Its performance parameters comply with ISO2858, and its technical requirements meet ISO5199.
Closed Impeller Pumps – Designed for clean liquids or media containing a small number of particles, especially suitable for fluids prone to crystallization or precipitation.
Open Impeller Pumps – Suitable for pulp with a density below 8%, fibers shorter than 50 mm, or other liquids with solid content below 30%. Large-channel open impellers can efficiently handle fibers, particles, or pulp.
Chemical pumps operate under extreme conditions, including acids, alkalis, high temperatures, and abrasive fluids. To ensure reliable performance, materials are carefully selected, including stainless steel (SS304, SS316, SS316L, 904), duplex stainless steel (CD4MCU, 2205, 2507), titanium, nickel, Monel, Hastelloy, and 20# alloy.

Product Details
Shaft Seal: Single or double cartridge mechanical seal, compliant with API 682, with optional seal support systems.
Volute: Straight tapered suction chamber with a uniform velocity field, minimizing hydraulic losses. The design of the suction chamber and guide plate reduces circumferential flow, lowers head loss, and improves efficiency.
Flange: ANSI/ASME/GOST B16.5 flange connections, designed to meet API dynamic nozzle loading limits.
Flush Nozzles: Compliant with API 682 flush plans, with integrated flush pipelines.
Seal Support System: Optional API seal support system (illustrated as API Plan 53B).
Bearing: Long-life antifriction roller bearings with oil bath lubrication and sealing.
Coupling with Spacer & Guard: Flexible coupling according to API 610/AGMA 9000 standards; bearing design only.
Electric Motor: IEC, NEMA, or EAC standard motors, with options for hazardous area applications.
Baseplate: Welded steel construction with sloping drip tray, drain connection, grounding points, and lifting attachments.
